Dispersion and localization in structured Rayleigh beams
A. Piccolroaz, A. B. Movchan
This paper brings a comparative analysis between dynamic models of couple-stress elastic materials and structured Rayleigh beams on a Winkler foundation. Although physical phenomen…
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…
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…
Effective elastic properties of planar SOFCs: A non-local dynamic homogenization approach
A. Bacigalupo, L. Morini, A. Piccolroaz
The focus of the article is on the analysis of effective elastic properties of planar Solid Oxide Fuell Cell (SOFC) devices. An ideal periodic multi-layered composite (SOFC-like) r…
