A dynamical interpretation of flutter instability in a continuous medium
Andrea Piccolroaz, Davide Bigoni, John R. Willis
Flutter instability in an infinite medium is a form of material instability corresponding to the occurrence of complex conjugate squares of the acceleration wave velocities. Althou…
An elastoplastic framework for granular materials becoming cohesive through mechanical densification. Part II - the formulation of elastoplastic coupling at large strain
Andrea Piccolroaz, Davide Bigoni, Alessandro Gajo
The two key phenomena occurring in the process of ceramic powder compaction are the progressive gain in cohesion and the increase of elastic stiffness, both related to the developm…
An elastoplastic framework for granular materials becoming cohesive through mechanical densification. Part I - small strain formulation
Andrea Piccolroaz, Davide Bigoni, Alessandro Gajo
Mechanical densification of granular bodies is a process in which a loose material becomes increasingly cohesive as the applied pressure increases. A constitutive description of th…
Yield criteria for quasibrittle and frictional materials
Davide Bigoni, Andrea Piccolroaz
A new yield/damage function is proposed for modelling the inelastic behaviour of a broad class of pressure-sensitive, frictional, ductile and brittle-cohesive materials. The yield…
Interaction of an interfacial crack with linear micro-defects under out-of-plane shear loading
Gennady Mishuris, Alexander Movchan, Natasha Movchan +1
The interaction of an interfacial crack with small impurities is analysed on the basis of an asymptotic formula derived by the authors. The interaction between the main crack and t…
Mode III interfacial crack in the presence of couple stress elastic materials
Andrea Piccolroaz, Gennady Mishuris, Enrico Radi
In this paper we are concerned with the problem of a crack lying at the interface between dissimilar materials with microstructure undergoing antiplane deformations. The micropolar…
