Elastic - Plastic Fracture Mechanics. Part 2. Marine Structural Applications

Abstract

This document contains the results of experimental and analytical studies of fracture in the ductile-brittle transition zone for two ship steels, EH36 and HSLA 80. Tensile, Charpy and fracture toughness test results using different strain rates are presented. fracture toughness was quantified by the J integral and the crack tip opening displacement (CTOD). Elastic-plastic finite element analysis was combined with a local failure criterion to derive size limits for J and CTOD testing in the transition regions. Relationships between J and CTOD testing in the transition regions. Relationships between J and CTOD were explored both experimentally and analytically. A theoretical Charpy-fracture toughness relationship was used to predict CTOD transition curves for the steels. Charpy and CTOD transition temperatures were compared for a number of steels.
