Energy and morphology of martensite-twinned martensite interface in CuAlNi shape memory alloy: a phase-field study
Seyedshoja Amini, Mohsen Rezaee-Hajidehi, Stanislaw Stupkiewicz
Needle-like twins are observed experimentally within the transition layer at the martensite-twinned martensite interface. We utilize a phase-field approach to investigate this micr…
Finite-strain formulation and FE implementation of a constitutive model for powder compaction
S. Stupkiewicz, A. Piccolroaz, D. Bigoni
A finite-strain formulation is developed, implemented and tested for a constitutive model capable of describing the transition from granular to fully dense state during cold formin…
Implicit yield function formulation for granular and rock-like materials
S. Stupkiewicz, R. Denzer, A. Piccolroaz +1
The constitutive modelling of granular, porous and quasi-brittle materials is based on yield (or damage) functions, which may exhibit features (for instance, lack of convexity, or…
Elastoplastic coupling to model cold ceramic powder compaction
S. Stupkiewicz, A. Piccolroaz, D. Bigoni
The simulation of industrial processes involving cold compaction of powders allows for the optimization of the production of both traditional and advanced ceramics. The capabilitie…
