The effect of the yield to tensile strength ratio on stress/strain concentrations around holes in high-strength steels

Application of high-strength steels in the maritime and offshore industry is currently limited by rules governing the ratio of the yield to tensile strength (the Y/T ratio). To better understand the physical basis for these rules, the nature and extent of the plastic stress/strain field in the vicinity of a stress concentration (a circular...

The effect of the yield to tensile strength ratio on the stress field in stress/strain concentrations around holes in steel structures

The aim of this thesis is to determine the influence of the Y/T, yield to tensile strength, ratio on the stress fields of high strength steels. This is relevant to the offshore industry as regulations restrict the use of steels with a high yield to tensile strength ratio, which is a characteristic of high­-strength and<br/>ultra high­-strength...
