Dynamic crack bifurcation in pmma
WebMay 7, 2010 · In coming sections, the experimental work done by Shioya and Zhou ( 1995) on dynamic crack propagation in PMMA plates is briefly reviewed. Following this, the DLSM methodology and the proposed rate-dependent cohesive law are explained in detail. Finally, the developed numerical model is used to reproduce the laboratory data. WebSep 24, 2013 · A finite volume/cohesive zone formulation was used to model micro-crack nucleation and dynamic interaction in the process zone. The cohesive strength and fracture resistance were estimated from unnotched tensile tests and the application of LEFM to the notch test data.
