Abstract

This presentation introduces an innovative modular approach to calibrating advanced material models, enabling the separate optimization of key mechanical phenomena—elasticity, plasticity, and material failure. Originally developed for Abaqus, our approach is readily extendable to other FEM platforms through an internally scripted tool that centralizes and simplifies the calibration process across different FEM solvers.

We will illustrate a couple of real projects e.g:

• Calibration of the Abaqus model of aluminum / DruckerPrager plasticity + Tresca–like yield surface for precise simulation of the crimping process
• Calibration of failure material model of the dual-phase steel sheets for automotive in Abaqus and comparison with Gissmo
• And more

We aim to inspire conference participants to think about this modular strategy that enhances the consistency of the results and improves process efficiency.

Presenter Bio

Ondrej Marada developed an interest in finite element calculations during his university studies. Over 14 years at IDIADA, he worked in various departments, ranging from NVH to crash. He contributed to the certification of the L410NG aircraft in the Fatigue and Damage Tolerance department at LET.

Currently, Ondrej is part of the materials team, focusing on delivering material models that accurately describe the real behavior of metals and plastics. Additionally, he supports the Czech representation of SIMULIA by providing customer support, training, and tailored solutions to their challenges.
