Microstructure sensitive fatigue life prediction model for SLM fabricated Hastelloy-X
Chandrashekhar M. Pilgar, Ana Fernandez, Javier Segurado
A microstructure-sensitive fatigue life prediction framework based on CP-FFT is proposed to study SLM fabricated Hastelloy-X. The microstructure enters in the model through the sha…
A generalized line tension model for precipitate strengthening in metallic alloys
R. Santos-Güemes, J. Segurado, J. LLorca
A generalized line tension model has been developed to estimate the critical resolved shear stress in precipitation hardened alloys. The model is based in previous line tension mod…
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-based approach for Bloch wave analysis: application to polycrystals
J. Segurado, R. A. Lebensohn
A method based on the Fast Fourier Transform is proposed to obtain the dispersion relation of acoustic waves in heterogeneous periodic media with arbitrary microstructures. The mic…
A multiplicative finite strain crystal plasticity formulation based on additive elastic corrector rates: Theory and numerical implementation
Meijuan Zhang, K. Nguyen, Javier Segurado +1
The purpose of continuum plasticity models is to efficiently predict the behavior of structures beyond their elastic limits. The purpose of multiscale materials science models, amo…
Multiscale modelling of precipitation hardening in Al-Cu alloys: dislocation dynamics simulations and experimental validation
R. Santos-Güemes, B. Bellón, G. Esteban-Manzanares +3
The mechanisms of dislocation/precipitate interactions were analyzed in an Al-Cu alloy containing a homogeneous dispersion of precipitates by means of discrete dislocation dyn…
