The following is an excerpt.
SFI CASA will host DYMAT’s 23rd Technical Meeting from 12 to 14 September 2017. The theme is Dynamic Fracture of Ductile Materials and abstract submission deadline is 15 January.
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.
The main objective with this technical meeting is 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 means materials and structures subjected to loading at elevated rates of strain combined with high and low temperatures and high pressures.
