Dynamic Fracturing Simulation of Brittle Material using the Distinct Lattice Spring Method with a Fu

Tohid Kazerani & Gaofeng Zhao & Jian Zhao

A full rate-dependent cohesive law is implemented in the distinct lattice spring method (DLSM) toinvestigate the dynamic fracturing behavior of brittlematerials. Both the spring ultimate deformation and springstrength are dependent on the spring deformation rate. Fromthe simulation results, it is found that the dynamic crackpropagation velocity can be well predicted by the DLSMthrough the implemented full rate-dependent cohesive law.Furthermore, a numerical investigation on dynamicbranching is also conducted by using the DLSM code.
