A criterion for slip transfer at grain boundaries in Al
R. Alizadeh, M. Peña-Ortega, T. R. Bieler +1
The slip transfer phenomenon was studied at the grain boundaries of pure Aluminum by means of slip trace analysis. Either slip transfer or blocked slip was analyzed in more than 25…
High fidelity simulation of the mechanical behavior of closed-cell polyurethane foams
M. Marvi-Mashhadi, C. S. Lopes, J. LLorca
The mechanical behavior of closed-cell foams in compression is analyzed by means of the finite element simulation of a representative volume element of the microstructure. The digi…
A coupled model of diffusional creep of polycrystalline solids based on climb of dislocations at grain boundaries
M. Magri, G. Lemoine, L. Adam +1
A continuum theory based on thermodynamics has been developed for modeling diffusional creep of polycrystalline solids. It consists of a coupled problem of vacancy diffusion and me…
The rotating rigid body model based on a non-twisting frame
Cristian Guillermo Gebhardt, Ignacio Romero
This work proposes and investigates a new model of the rotating rigid body based on the non-twisting frame. Such a frame consists of three mutually orthogonal unit vectors whose ro…
Simulation of the Hall-Petch effect in FCC polycrystals by means of strain gradient crystal plasticity and FFT homogenization
S. Haouala, S. Lucarini, J. LLorca +1
The influence of grain size on the flow stress of various FCC polycrystals (Cu, Al, Ag and Ni) has been analyzed by means of computational homogenization of a representative volume…
Basal dislocation/precipitate interactions in Mg-Al alloys: an atomistic investigation
Gustavo Esteban-Manzanares, Anxin Ma, Ioannis Papadimitriou +2
The interaction between edge basal dislocations and -MgAl precipitates was studied using atomistic simulations. A strategy was developed to insert a lozenge-shaped…
