Study on Model of Meso-Scale Simulation for Aircraft Structure Material Based on Voronoi Algorithm

Abstract:

Multi-scale theory and framework in research of fatigue crack is described, and then in meso-scale the simulation model of polycrystalline material grains is established using Voronoi algorithm, and the feasibility of this algorithm is verified at the same time; cohesive zone method is introduced and cohesive strength on the interface along grain boundaries is discussed, then Young´s modulus is tried to define in meso-scale according to cohesive zone method, which prepares the calculation of the finite element model.
