An FFT-based crystal plasticity phase-field model for micromechanical fatigue cracking based on the stored energy density
Sergio Lucarini, Fionn P. E. Dunne, Emilio Martínez-Pañeda
A novel FFT-based phase-field fracture framework for modelling fatigue crack initiation and propagation at the microscale is presented. A damage driving force is defined based on t…
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…
An FFT framework for simulating non-local ductile failure in heterogeneous materials
M. Magri, S. Lucarini, G. Lemoine +2
The simulation of fracture using continuum ductile damage models attains a pathological discretization dependence caused by strain localization, after loss of ellipticity of the pr…
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…
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…
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…
