Crack Analysis of the Quasi-Brittle Materials Using a Stochastic Model

물성의 확륙적 분포를 이용한 Quasi-Brittle 재료의 균열해석

Usually, the failure of quasi-brittle materials is numerically difficult to describe because of the localization process with softening behavior. In this study, ADLE(Axial Deformation Link Elements) with stochastic material properties are developed to simulate the quasi-brittle material failure behavior. The ADLE method is adopted both Fictitious Crack Model and stochastic method to implement the fracture behavior with the localization behavior of quasi-brittle materials. The main objective of this paper is to show the mash independency and the capability of ADLE for the failure behavior of a quasi-brittle materials.
