Thermo-mechanical response FEM simulation of ceramic refractories undergoing severe temperature variations
Theodosios K. Papathanasiou, Francesco Dal Corso, Andrea Piccolroaz
The development of thermal stresses inside refractory ceramics experiencing severe thermal shock is studied. The present analysis departs from the linear theory of thermal stresses…
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…
Boundary integral formulation for interfacial cracks in thermodiffusive bimaterials
L. Morini, A. Piccolroaz
An original boundary integral formulation is proposed for the problem of a semi-infinite crack at the interface between two dissimilar elastic materials in the presence of heat flo…
Multiscale asymptotic homogenization analysis of thermo-diffusive composite materials
A. Bacigalupo, L. Morini, A. Piccolroaz
In this paper an asymptotic homogenization method for the analysis of composite materials with periodic microstructure in presence of thermodiffusion is described. Appropriate down…
Strain localization and shear banding in ductile materials
N. Bordignon, A. Piccolroaz, F. Dal Corso +1
A model of a shear band as a zero-thickness nonlinear interface is proposed and tested using finite element simulations. An imperfection approach is used in this model where a shea…
