A study about the application limit of Non-Linear Crack Mechanics

Abstract

In this study, I investigate an application limit of Non-Linear Crack Mechanics (NLCM). NLCM is applied up to an equivalent plastic strain value of about 30%. Therefore, NLCM is applied to the equivalent plastic strain value of about 45% for verification. NLCM was applied to a strip with a crack in the center up to an equivalent plastic strain value of about 45%. As a result, NLCM can be applied to the equivalent plastic strain value of about 45% for two types of problems of strips with a center crack.
