FEM Simulation Engineer

Experienced Computational Physicist with over two years of specialized experience in Finite Element Method (FEM), numerical simulation, and multiphysics modeling. Expertise in developing and validating mechanical and thermomechanical FEM models, as well as analyzing strength, fatigue, and material behavior. Proficient in using tools such as LS-DYNA, ANSYS, COMSOL Multiphysics, Python, and MATLAB. Passionate about developing innovative mechanical solutions, particularly in the energy and electromobility sectors.

Development and validation of nonlinear, anisotropic FEM models in LS-DYNA for strength, failure, fatigue, and thermomechanical analyses with high correlation to experimental results. Implementation and validation of temperature- and strain-rate-dependent material models, confirmed by mechanical and thermal tests (tensile testing machine, DIC, thermography). Conception and execution of DoE-based experimental-numerical studies using Cornerstone to investigate material behavior and failure mechanisms. Automation of FEM pre- and post-processing and data extraction using Python and MATLAB scripts. Execution of multiphysics simulations of electronic components using COMSOL Multiphysics, including comparison and calibration with Silvaco simulations and experimental data. Analysis of electrical properties of bipolar transistors and SiGe heterojunction bipolar transistors (HBTs) and investigation of heating effects.
