Nonlocal Approach to CAFE Solution of Creep Crack Growth Problem

Krzysztof NOWAK
Cracow University of Technology

Solving a creep crack growth problem using the CAFE methodology encounters the problems typical of other local methods. This article presents a nonlocal grid method applied in order to regularize these problems. The subject of the analysis is a rectangular plate with a central hole and an internal crack. The results obtained for different mesh sizes have subsequently been compared.
Keywords: nonlocal method; grid method; CAFE; creep damage
