Adaptation and validation of FFT methods for homogenization of lattice based materials
S. Lucarini, L. Cobian, A. Voitus +1
An FFT framework which preserves a good numerical performance in the case of domains with large regions of empty space is proposed and analyzed for its application to lattice based…
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…
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…
Crystal plasticity simulation of the effect of grain size on the fatigue behavior of polycrystalline Inconel 718
A. Cruzado, S. Lucarini, J. LLorca +1
A microstructure-based model that accounts for the effect of grain size has been developed to study the effect of grain size on the fatigue life of Inconel 718 alloys. The fatigue…
Microstructure-based fatigue life model of metallic alloys with bilinear Coffin-Manson behavior
A. Cruzado, S. Lucarini, J. LLorca +1
A microstructure-based model is presented to predict the fatigue life of polycrystalline metallic alloys which present a bilinear Coffin-Manson relationship. The model is based in…
