A Model for Predicting the Multiscale Crack Growth Due to an Impact in Heterogeneous Viscoelastic Solids
نویسندگان
چکیده
A two-scale model for predicting the multiple crack growth in viscoelastic solids due to an impact is presented. The cracks are considered only at the local scale through the use of a micromechanical viscoelastic cohesive zone model. The multiscale model has been implemented in a finite-element code. In order to minimize the computation time, the local finite-element meshes are solved in parallel by multiple processors. An example problem is given in order to demonstrate the capabilities of the model.

متن کاملApplication of Multiscale Cohesive Zone Model to Simulate Fracture in Polycrystalline Solids
In this work, we apply the multiscale cohesive method (Zeng and Li [2010]) to simulate fracture and crack propagations in polycrystalline solids. The multiscale cohesive method uses fundamental principles of colloidal physics and micro-mechanics homogenization techniques to link the atomistic binding potential with the mesoscale material properties of the cohesive zone, and hence the method can...
