Cohesive Modeling of Dynamic Fracture: Rate Dependence and Intersonic Crack Motion
… Results show that exclusive shear damage in the cohesive zone is responsible for intersonic crack propagation even though the external load comprises of both shear and tensile components. The situation is very different in the subsonic regime, where crack motion is a result of combined shear and …

Extrinsic Cohesive Modeling of Dynamic Fracture and Microbranching Instability Using a Topological Data Structure
… in a variety of materials by incorporating a Cohesive Zone Model (CZM) into the finite clement scheme, The CZM failure criterion uses both a finite cohesive strength and work to fracture in the material description. Based on crack initiation criteria, CZMs can be categorized into two groups, …

Modeling the effect of debonding on the constitutive response of heterogeneous materials
… insights into the physics of dewetting. The two modeling approaches are compared for the axisymmetric case of circular particles debonding under equibiaxial loading. MTH simulations were used to provide a reference solution against which the micromechanics results could be evaluated. The …
