Analysis and numerical simulation of plastic deformation of single crystals and TWIP-alloys within the continuum dislocation theory

• Applicant: Professor Dr. Khanh Chau Le
• Subject Area: Mechanical Properties of Metallic Materials and their Microstructural Origins
• Term: from 2012 to 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 213252453

In this project the mechanical behavior of single crystals and TWIP-alloys due to the collective nucleation of dislocations within the continuum dislocation theory (CDT) should be analyzed and numerically simulated. The aim is to predict the size effects of the yield stress, work hardening, and hardness as well as the accompanying change of microstructure (twin formation, polygonization, recrystallization) for arbitrary geometry of the specimen and loading condition in terms of the energy and dissipation.
