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…
Effect of slip transmission at grain boundaries in Al bicrystals
S. Haouala, R. Alizadeh, T. R. Bieler +2
The effect of slip transfer on the deformation mechanisms of Al bicrystals was explored using a rate-dependent dislocation-based crystal plasticity model. Three different types of…
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…
DBFFT: A displacement based FFT approach for non-linear homogenization of the mechanical behavior
Sergio Lucarini, Javier Segurado
Most of the FFT methods available for homogenization of the mechanical response use the strain/deformation gradient as unknown, imposing their compatibility using Green's functions…
Development of a thermo-mechanically coupled crystal plasticity modeling framework: application to polycrystalline homogenization
Jifeng Li, Ignacio Romero, Javier Segurado
Accurate predictions of thermo-mechanically coupled process in metals can lead to a reduction of cost and an increase of productivity in manufacturing processes such as forming. Fo…
An algorithm for stress and mixed control in Galerkin based FFT homogenization
S. Lucarini, J. Segurado
A new algorithm is proposed to impose a macroscopic stress or mixed stress/deformation gradient history in the context of non-linear Galerkin based FFT homogenization. The method p…
