Local Approach for Elastic-Plastic Fracture Assessment of Cracked Component Under Mixed Mode Loading
Paper presented at the The 29th International Ocean and Polar Engineering Conference, June 16–21, 2019
Paper Number: ISOPE-I-19-192
... ABSTRACT A unique criterion to evaluate brittle fracture resistance of cracked components under large scale yielding condition irrespective of loading modes has not been established. The critical Weibull stresses estimated with a original Beremin model based on a linear fracture mechanics...

Paper presented at the The Twenty-fifth International Ocean and Polar Engineering Conference, June 21–26, 2015
Paper Number: ISOPE-I-15-436
... Abstract This paper concerns the applicability of two approaches for prediction of brittle fracture in the beam-to-column connection. One is a method using Weibull stress approach, the other is a method based on toughness scaling model (TSM). The experiments using beam-tocolumn joint models...
