Mobility

Dr. Jakub Luštinec

Sending institution: Faculty of Nuclear Sciences and Physical Engineering, Czech Technical University in Prague
Host institution: Kanazawa University, Kanazawa, Japan
Mentor: Prof. Tatsuki Oda
Period of mobility: 3/2024 – 8/2024
Abstract: We have a long-term collaboration with the group of Tatsuki Oda: a joint publication on Ni-Mn-Ga and shared doctoral research. The group focuses on the electronic structure of ferroelectric materials, using their own electronic structure code based on Green’s functions, which is more accurate than standard DFT codes. The goal is to calculate the electronic structure of ferroelectric materials (magnetic alloys) with their code and compare the results with the SPR-KKR code.

Dr. Tomáš Grabec

Sending institution: Institute of Thermomechanics, Czech Academy of Sciences
Host institution: ReceNDT Linz, Linz, Austria
Mentor: Dr. Martin Ryzy
Period of mobility: 9/2024 – 11/2024
Abstract: A research visit in the laboratory of Prof. Peter Burgholzer aimed at the joint development of a laser–ultrasonic method for characterizing the microstructure and mechanical properties of materials, based on determining the frequency of local plate vibration modes (so-called zero group velocity modes, ZGV) and surface acoustic waves, together with the development of a numerical method for processing the measured data and applying it in an inverse approach to determine material properties.The mobility will enable close collaboration on the development of both tools (experimental and computational parts) for the initial phase of the method and the first tests on measured data. At the same time, FEM simulations will be tested to generate virtual data and to deepen the understanding of the generation and propagation of these specific modes of mechanical waves.

Dr. Jiří Kozlík

Sending institution: Faculty of Mathematics and Physics, Charles University, Prague, Czech Republic
Host institution: Institute of Fundamental Technological Research of the Polish Academy of Sciences (IPPT PAN), Warsaw, Poland
Mentor: Prof. Jerzy Rojek
Period of mobility: 1/2025 – 6/2025
Abstract: The research stay will focus on modeling the formation and development of the athermal ω phase, its influence on the chemical composition of β-stabilized Ti alloys, and the mutual interaction of individual precipitates on the micro- and nano-scale. An essential part of this internship will be the development of thermodynamic potentials that describe these processes.

Host institution: Nothern Arizona University, Flagstaff, USA
Mentor: Prof. Heidi Feigenbaum, Ph.D.
Period of mobility: 6/2025 – 7/2025
Abstract: A research stay in the laboratory of the team led by Prof. Heidi Feigenbaum at Northern Arizona University, AZ, USA, with the aim of knowledge transfer. The specific objectives are: (i) finalizing the numerical implementation of the kinematic hardening model with anisotropic plasticity, (ii) developing experimental procedures for the validation of plasticity models, and (iii) identifying current challenges in numerical and experimental plasticity and exploring new common topics and directions of development.

Dr. Petr Šesták

Sending institution: Institute of Thermomechanics, Czech Academy of Sciences
Host institution: Norwegian University of Science and Technology, Trondheim, Norway
Mentor: Senbo Xiao
Period of mobility: 7/2025 – 8/2025
Abstract: This collaboration involves the team of Prof. Zhiliang Zhang – Nanomechanical Lab. The focus of the new research stay is to gain advanced expertise in molecular dynamics modeling using the LAMMPS program, which is actively employed in the FerrMion project for simulating the martensitic phase of NiTi alloys with machine-learned potentials. The specific objectives of this stay are: the development of advanced models of the martensitic phase of NiTi alloys suitable for molecular dynamics; acquiring in-depth knowledge of modeling with the LAMMPS program; expanding the current dataset used for training potentials for molecular dynamics; consulting and verifying the baseline NiTi martensite models already created.
