Abstract
Continuum fracture mechanics concepts should be applied to solve dynamic fracture problems wherever a continuum approach can provide sufficient answers. Many dynamic fracture problems, however, involve multiple cracks or voids and are not well-suited to the relatively simple continuum approach. This paper describes a statistical fracture mechanics concept on a microscopic scale and illustrates its use for the case of shock-wave-induced ductile spall fracture. The paper further shows how micro-statistical fracture mechanics (MSFM) merges with continuum fracture mechanics by treating a macrocrack propagating in a DCB specimen using MSFM and the MSFM parameters deduced from the spall work.
