Abstract Since crystal plasticity is the result of moving and interacting dislocations, it seems self-evident that continuum plasticity should in principle be derivable as a statistical continuum theory of dislocations, though in practice we are stil

A computational study is conducted to examine the influence of mechanical twins on the kinetics of martensitic transformation in TRIP-maraging steel. Simulations are performed using a non-local crystal plasticity (CP) phase transformation model descr

Negative strain rate sensitivity (NSRS) leading to the strain localization and ultimately failure of material is one of the greatest challenges in the efficient usage of the Al alloys. NSRS in Al-Cu alloy (AA2024) is investigated with the help of uni

International audience; We develop a crystal plasticity model to investigate the coupled actions of crystal orientation, grain neighborhood and grain-to-grain elasto-plastic interactions on dynamic strain aging (DSA) and the onset and development of

We develop a dislocation density based crystal plasticity model to capture the micromechanical behavior of γ′ strengthening nickel-based superalloys. The elasto-viscoplastic model presented here accounts for hardening behavior of both γ and γ′

The displacement discontinuity arising between crack surfaces is assigned to smooth densities of crystal defects referred to as disconnections, through the incompatibility of the distortion tensor. In a dual way, the disconnections are defined as lin

Influence of crystal orientation on bending size effect has been numerically investigated for single crystal beams. This work is inspired by the experimental observations of Hayashi et al. (2011), where they observed a significant difference in bendi
