Summary:Ultimate strength evaluation for cracked plates is examined. A rectangular plate including a through-crack under uni-axial compression load is assumed. In analyzing the cracked plate, shell finite element (FE) modeling and shell-solid FE modeling are respectively adopted. Contact condition is included in the shell-solid modeling to introduce the crack-closure effect. Numerical examples are presented for analyzing accuracy in the FE modeling and investigating buckling and post-buckling behaviors of the cracked plates by changing position and length of the through-crack.
