Deformation of the Crack Front during Propagation in Some is Ordered Medium: Theoretical and Experimental Studies
Abstract: In heterogeneous disordered materials, a straight crack front experiences toughness fluctuations during its propagation that generate geometric fluctuations. Their longtime statistical behavior has been studied by Lazarus et al. (JMPS,2008) using Bueckner-Rice weight function theory. In particular, the evolution of the auto correlation function, power spectrum and variance of the front fluctuations have been […]
