The following is an excerpt.
More than 100 participants from 16 countries on three continents took part in the 23rd DYMAT Technical Meeting earlier this month. The meeting took place in Trondheim with SFI CASA as host.
DYMAT being an organization for the study of dynamic behaviour of materials with aspects such as experimental techniques, constitutive modelling, micro-structural effects and numerical simulations, this year’s technical meeting focused on dynamic fracture of ductile materials.
Main objective
The main objective of the 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. The meeting concentrated on four themes:
Dynamic testing and characterization
Hopkinson Bar Techniques, high speed and ultra-high speed cameras, full-field measurements, impact experiments and extreme loading conditions.
Modelling of damage and fracture
Continuum damage mechanics, porous plasticity, micromechanical modelling, multi-scale approaches.
Numerical methods
Mesh-free methods, X-FEM, ALE, particle methods.
Applications
Automotive, oil and gas, safety of buildings and structures, armour solutions, natural hazards, industrial processes including machining.
