Project is aimed at precise simulations for training of physics-informed machine learning schemes in optimization of materials with respect to deformation energy mitigation. Advanced finite element simulations methods with state-of-the-art techniques of dynamic testing are combined for investigation of intermediate and high strain rate impact response of materials with complex internal structure in relation to machine learning applications. The investigated materials are additively manufactured structures, including auxetic lattices, and inter-penetrating composites. Experimental methods involve flash and high-speed X-ray radiography togetherwith high speed visible-light and infrared cameras. The numerical methods using finite element methods with explicit time integration will enable physically accurate simulations of loading scenarios and in-house solver for unprecedented insight into wave propagation in materials during impact will be developed. Moreover, simulations of radiographical methods will allow tosimulate all aspects of experiments.

Annotation:
The project is aiming to control the stress wave propagation in additively produced metal components composed of at least two different metals with spatially shaped and multiple interfaces produced by laser powder bed fusion. This enables to control of internal arrangement and shaping of the interface between the two materials. Dynamic loading with different strain rates using Hopkinson pressure bars will be used to describe the stress wave propagation and kinetic energy absorption. At the same time, theoretical and numerical modelling of wave reflection/transmission will be performed on various geometrically arranged interfaces. Innovative numerical tools for advanced multi-material optimization of nested spatial structures will be developed for wave process control. The results will answer the questions of whether it is possible to control the propagation of stress waves by means of multi-material 3D metal printing, and what geometrical and mechanical parameters have a fundamental influence on the attenuation and concentration of stress waves.

Annotation:
The project is focused on investigation of time-dependent processes influencing mechanical properties and internal structure of advanced engineering materials. Combination of analytical, numerical and experimental methods will be used for determination of relations between mechanical properties and microstructure of studied materials. In the theoretical part analytical and numerical methods will be implemented and techniques for evaluation of effective quasi-static and dynamic response of the studied materials will be developed. Experimental methods will involve enhancement of applications for processing and evaluation of experiments and also design of specialized measurement devices. These methods will be suitable for optimisation of the usage of advanced materials with microstructure in transportation applications and their safe operation.

Konference 13th Youth Symposium on Experimental Solid Mechanics je setkáním mladých vědeckých pracovníků, doktorandů a studentů z evropských i mimoevropských univerzit a výzkumných center. Z ČVUT jsou registrováni účastníci z fakulty dopravní, strojní, stavební a jaderné a fyzikálně inženýrské. Jedná se o tradiční prezentaci prací především v oblasti experimentální mechaniky. Konkrétně se jedná o následující témata: - Pokročilé experimentální metody mechaniky kontinua a mechaniky tekutin - Nedestruktivní zkoušení - Lomová mechanika, poruchy materiálu - Biomechanika - Hybridní numericko-experimentální metody - Problematika technologických procesů - Mikro- a nano- aplikace Cílem konference je prezentace výsledků výzkumu, výměna zkušeností a navazování kontaktů. Výsledky jsou prezentovány formou komentovaných posterů doplněných vyzvanými přednáškami předních odborníků (letos K.H. Laermann, J. Lukeš). Na základě diskuze nad řešenými tématy vznikají návrhy na mezinárodní výzkumné projekty nebo stáže jednotlivých účastníků. Všechny příspěvky projdou před publikováním standardním peer-review procesem, pro nemalou část účastníků prvním v jejich publikační činnosti. Sborník plných textů bude zaslán k zařazení do databáze WoS. Autoři nejlepších příspěvků budou vyzváni k podání rozšířených verzí svých příspěvků do časopisu Measurement (IF 1.13).

Annotation:
The aim of the project is focused on development of the methods for quantification of heterogeneous materials behaviour. This method will be used for determination of relations between mechanical and structural properties. The first goal is description of basic constitutive relations of advanced materials, the second goal is application on assessment of reactions to external loading. Preferably, nondestructive experimental methods and methods of image processing will be investigated. Investigation will be concentrated on observation of external environment influences on material microstructure. These methods will be useful for diagnostics and lifecycle predictions that are the key factor for transport systems safety.
