BACKGROUND

Numerical simulations have moved into a leading role in engineering system design due to the pressure towards decreasing the time and cost of bringing products to the market. The success of numerical simulations for innovation and value creation relies among other things on the quality of the material modelling. Constitutive models describe the stress and internal variables as function of the strain, strain rate and temperature. In large-scale simulations of structures, the framework of continuum thermo-mechanics is typically adopted to formulate the constitutive models, while thermo-mechanical testing is used to identify the model parameters. The models have to describe plastic anisotropy, non-linear isotropic and kinematic hardening, strain-rate and temperature dependence, damage evolution and failure. Thus a basic understanding of the physical phenomenon controlling the material response is necessary in large-scale analysis as well as an understanding of how simplifications can be made to still retain sufficient accuracy reliability.

 

OBJECTIVE

The main objective with this technical meeting was to gather scientists and PhD students to provide state-of-the-art knowledge on constitutive models for damage and fracture of ductile materials subjected to dynamic loading. Dynamic loading in this context was defined as materials and structures subjected to loading at elevated rates of strain combined with high and low temperatures and high pressures.
