Plastically-driven variation of elastic stiffness in green bodies during powder compaction. Part II: Micromechanical modelling
L. P. Argani, D. Misseroni, A. Piccolroaz +2
A micromechanical approach is set-up to analyse the increase in elastic stiffness related to development of plastic deformation (the elastoplastic coupling concept) occurring durin…
Plastically-driven variation of elastic stiffness in green bodies during powder compaction: Part I Experiments and elastoplastic coupling
L. P. Argani, D. Misseroni, A. Piccolroaz +3
Cold compaction of ceramic powders is driven by plastic strain, during which the elastic stiffness of the material progressively increases from values typical of granular matter to…
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…
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…
