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…
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…
High-throughput extraction of the anisotropic interdiffusion coefficients in hcp Mg-Al alloys
Jingya Wang, Weisen Zheng, Guanglong Xu +2
A high-throughput experimental approach is presented to extract the anisotropic interdiffusion coefficient by combining information over the composition profiles obtained by the el…
Effect of Grain Orientation and Local Strains on Void Growth and Coalescence in Titanium
Marina Pushkareva, Federico Sket, Javier Segurado +3
Ductile fracture has been extensively studied in metals with weak mechanical anisotropy such as copper and aluminum. The fracture of more anisotropic metals, especially those with…
