3D simulations of the interactions between crack and dislocations
The thesis is incorporated within the framework of the Work package 2 of the microKIc Project entitled: Development and Application of a Discrete Dislocation – Crack Dynamics (DDD+C) Model. This Work Package will be done in close interaction with the WP1: Atomistic Simulations of Static and Dynamic Cracks and WP3: Micromechanical Fracture Testing carried out in Germany within the FAU. The objective is to implement a crack propagation model in the DDD code developed in SIMaP for body-centered cubic materials in the thermal activated state. After validation in a static loading scenario, the code will be expanded to take into account crack propagation. A lead is to use a cohesive zone model based on energy-displacement curves which will be provided by atomic simulations attained in FAU Nurnberg.
