Project

Molecular dynamic simulations of brittle-ductile behaviour of microcracks in 2D and 3D (IAA2076201)

The project is motivated by efforts to understand the brittle-ductile behaviour of crystalline materials. Molecular dynamic simulations of 2D and 3D problems with various loading will be utilized to study: the brittle (fast...
