Experimental investigation of the elastoplastic response of aluminum silicate spray dried powder during cold compaction
F. Bosi, A. Piccolroaz, M. Gei +3
Mechanical experiments have been designed and performed to investigate the elasto-plastic behaviour of green bodies formed from an aluminum silicate spray dried powder used for til…
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…
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…
Integration algorithms of elastoplasticity for ceramic powder compaction
M. Penasa, A. Piccolroaz, L. Argani +1
Inelastic deformation of ceramic powders (and of a broad class of rock-like and granular materials), can be described with the yield function proposed by Bigoni and Piccolroaz (200…
A simple and robust elastoplastic constitutive model for concrete
F. Poltronieri, A. Piccolroaz, D. Bigoni
An elasto-plastic model for concrete, based on a recently-proposed yield surface and simple hardening laws, is formulated, implemented, numerically tested and validated against ava…
