MSD가 존재하는 시편에 대한 잔류강도 평가
Abstract
The residual strength of a specimen with MSD was investigated experimentally and numerically. The used materials for specimens are 2024-T3 and S50C. In each specimen, one main crack and 4 small cracks are machined by using electrical discharge wire cutting and saw cutting. The residual strengths are measured for 3 cases of crack configurations, and the measured values are compared with the values obtained numerically by using elasto-plastic average uncracked ligament stress link-up criteria.
