The minisymposium covers the newest outcomes and trends in damage detection, identification and modeling in the case of modern engineering materials and production technologies. Invitation to submit a presentation is addressed to wide group of scientists and engineers working on new methods for machining and effectiveness of production. Various engineering materials, such as light alloys, composites, wood, ceramics, polymers and others can be machined with many techniques: milling, turning, water-cutting, plasma-spraying, laser welding, 3D printing etc. In many cases, post-machining defects can emerge: surface roughness, residual stresses, cracks, pores, delamination and shape errors. In the face of growing demands for product quality, reliability and repeatability, any of the techniques for flaw detection and identification are of great meaning. In particular, the real time diagnostics based on X-ray (tomography), acoustic emission, thermography and vibrometry can bring out interesting and useful results. On the other hand, also post-production quality control tools are important, ex. fractography, ultrasonics and metrological methods. All these problems are welcome in this minisymposium as potentially advantageous in the process of engineering materials’ and technology development. Also advancements in modeling techniques, usually implemented in the Finite Element codes and the experimental outcomes are welcome.

Additive manufacturing, as 3D printing and the novel 4D-printing technology enable the production of highly precise prototypes with complex shape, unique capabilities and novel functions, for variety of applications. The concept of 4D-printing requires a material with specific physical and mechanical properties, sensitivity to external stimuli, and structural design with a selected 3D-printing technique. Nanofillers can introduce additional functions and improve properties and 3D printability. Although 3D and 4D printing are rapidly developing, many challenges remain to be overcome to move beyond laboratory prototypes and to fully realize their potential.

This mini-symposium aims to attract presentations on: Novel materials for 3D & 4D printing; Mechanical properties at macro, micro and nanoscale; Investigation of printed structures for applications in: structural health monitoring; heat transfer; heating elements; self-healing, self-actuating, etc.

Energy harvesting has received a lot of attention in the last few decades due to its promise in augmenting to the energy landscape by powering low-powered wireless
sensors or in generating self-power sensors. More than two decades of research has witnessed from linear to nonlinear vibrations based energy generation primarily using
piezo-electric, electromagnetic, transduction mechanisms. Sources of energy harvesters included light, thermal gradient, vibration, uid induced vortices, or combination there of.
Applications ranged from IoT devices, automation to self powered sensors. Many theoretical insights have been reported, many innovative devices were designed and

Within the framework of the 14th congress on theoretical and applied mechanics (14th NCTAM), which will be held from September 2 to 4 2024 in Sofia, is being organized the interdisciplinary Biomechanics, Biorheology and Biomathematics Symposium. The Symposium is dedicated to Prof. DSc. Svetoslav Markov (1943-2023) - an internationally recognized researcher and scientist in the field of applied mathematics, bioinformatics, computing in mathematics, natural science, engineering and medicine.
The purpose of the Symposium is to bring together researchers who are interested in theoretical and experimental investigations of the mechanical behavior of living systems. In particular, it includes the study of the human structures and functions on macro-, micro- and nano levels.
The Symposium aims to exchange experience and knowledge of scientists, developing and applying mathematical and computational tools to the study of phenomena in the broad fields of biomechanics, biorheology, bioengineering, biophysics, biochemistry, medicine, biology, biotechnology, environmental science, pharmacokinetics, cheminformatics, etc.

Some of the preliminary topics of the Symposium are:

•  Methods of non-linear continuum mechanics, of deterministic and statistical analyses of biomedical time series, of phase and bifurcation analyses of dynamical models, as well as 3D computer modeling and simulation of human motion.
•  Studies oriented to improve the diagnosis and therapy of certain diseases as orthopedic traumas, cardiovascular disorders and cancer as well as to design new elbow and ankle-foot orthoses.
• Studies of rheological and electrical behavior of blood and its formed elements, aimed to improve the methods and enhance the diagnostic tools in patients with diabetes, cerebrovascular diseases, atherosclerosis.
• Studies of mechanical behavior of biological tissues.
• Mathematical modeling based on experimental data aimed at discovering the dynamic nature and quantitative predictions of the response of signaling pathways and their disorders and finding potential drug targets.
• Developing, studying and using innovative materials, devices and systems inspired by biological systems and/or addressing biomedical requirements. Monitoring and diagnostics devices, sensors and instrumentation systems, biorobots and prosthetics, micro-nanotechnologies including microfluidics systems and biomaterials are some of the technologies addressed at this Symposium.

Numerous sensors are installed in a range of engineering structures like bridges to real-time acquisition of structural response such as deflection, displacement, strain, acceleration, etc., accumulating massive monitoring data. Noticeably, it is challenging to interpret monitoring data so as to reflect structural physical states. Most existing methods remain in the scope of signal processing, likely incapable of reflecting structural conditions. Especially, when these monitoring data are rashly inputted into artificial intelligence machine for damage identification, resulting in non-convergence in training or low accuracy of identification. This mini-symposium focuses on using mechanics as a tool to interpret massive monitoring data of structures. Interesting topics include but no limited to: mechanics-inspired interpretation of monitoring data, mechanics-driven damage interrogation, mechanics-underpinned intelligent identification of structural damage; mechanics-informed structural digital-twin models; mechanics & data-supported structural performance assessment.

Flow rates in the vascular system vary between scales of L/min in the large arteries to µL/hour in a typical lymph vessel and internal pressures can vary from +200 to -80 cmH2O, from which it follows that shear and circumferential stresses encompass a proportionately wide range. The mechanical properties of these tubular structures have evolved to withstand the applied circumferential and shear forces to which they are exposed and these properties change in response to alterations in these forces as a consequence of growth, development, ageing and disease – a process broadly described as remodelling. In addition to the relatively long term-response (>days) of blood and lymph vessels, their short-term behaviour (seconds – hours) depends on the contractile abilities of their constituent cells. In the blood vessels the main mechanical function of these cells is to control the heart-driven flow, and thus shear stress on the vessel walls, by local contraction or relaxation. On the other hand, in the lymph system, by concerted cyclical action, the vessels produce their own pumping, which together with local skeletal muscular activity, provides the driving force to maintain lymph flow.

Cardiovascular disease results from the disturbed behaviour of the cells in the heart and blood vessel walls, leading to disruption in their structure and mechanical properties. Once established, these changes further exacerbate the disease. In addition to its role in fluid balance, the lymphatic system serves as a communication network for immune function as well as a route for the dissemination of cancer cells. Lymph Nodes act as information collection/distribution hubs for immune function, with diffusive and flow-mediated processes required to distribute information effectively. Given that cardiovascular disease and cancer are the two major causes of premature death in the developed and developing world, there is an ever increasing need for improved understanding of the complex pathogenesis of these diseases from the molecular scale to macroscopic fluid flows and mechanical stresses.

 
This symposium will present recent theoretical and experimental work on blood vessel mechanical properties and remodelling, the mechanics of lymph flow and diagnostic devices to detect changes in fluid flow and vessel mechanics.
