A Model For Predicting The Multiscale Crack Growth Due To An Impact In Heterogeneous Viscoelastic Solids, Flavio V. Souza, David H. Allen

Department of Engineering Mechanics: Faculty Publications

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.
