A numerical process based on crystal plasticity finite element (CPFE) was implemented to predict creep-fatigue crack initiation life. CPFE-based model can describe the macroscopic cyclic deformation and reveal grain-level damage mechanism.

A dislocation density based crystal plasticity model is developed to account for the precipitate induced cyclic softening in IN718. The new model treats the interaction between the precipitates and the dislocations using a probabilistic approach.

A non-local crystal plasticity constitutive model for hexagonal close-packed polycrystals
, 2021A strain gradient crystal plasticity finite element model is developed to study the evolution of internal and localized elastic strains in hexagonal close-packed polycrystals. The results of the model are firstly compared to the previously published data

Micro-textured regions (MTRs) are the presence of large regions of α grains aggregates with strong local texture, which are detrimental to the fatigue performances in titanium alloys. This work proposes an EBSD map-image based crystal plasticity model to

Journal of Applied Mechanics, 1983
Significant progress has been made during the past decade in incorporating micromechanics in continuum descriptions of inelastic deformation. This has led to the development of a rather comprehensive constitutive theory for rate-dependent and idealized rate-independent crystalline materials that deform plastically by crystalline slip.

Crystal plasticity finite element analysis of gradient nanostructured TWIP steel
International journal of plasticity, 2020Although twinning induced plasticity (TWIP) steels have achieved a satisfactory combination of high strength and large plasticity, surface nanocrystallization realizes a further improvement of yield stress in TWIP steels without sacrificing much ...

Crystal plasticity based investigation of micro-void evolution under multi-axial loading conditions
International journal of plasticity, 2020The present work investigates the effects of stress state and crystallographic orientation of the principal stress axes on the growth behaviour of micro-voids embedded in an aluminium alloy single crystal.

Boundary Element Crystal Plasticity Method
Journal of Multiscale Modelling, 2017A three-dimensional (3D) boundary element method for small strains crystal plasticity is described. The method, developed for polycrystalline aggregates, makes use of a set of boundary integral equations for modeling the individual grains, which are represented as anisotropic elasto-plastic domains.
