A brief overview of our specific competences follows:

• Quantitative constitutive material models for different materials (aluminium alloys, polymers)
• Numerical algorithms for integrating these material models resulting in FORTRAN-codes – user material subroutines – that can be compiled with different non-linear finite element codes
• FE-based crystal plasticity for metallic materials
• Parameter identification and visualisation programs for anisotropic yield criteria, strain hardening and strain rate hardening models, and dynamic strain hardening models
• Test matrix for complete characterisation of elasto-plasticity and fracture, based on in-house research.
• Partly parameterised element models of generic test set-ups
• Experimental and modelling protocols for all existing test methods together with extensive databases (ongoing work)
• Procedures for characterisation of surface roughness and evaluation of the influence on fatigue life
• Procedures for generating element models from 2D and 3D measurements
