Elastic-plastic stress states on double-edge-notched tensile specimens are analyzed by the three-dimensional finite element method. Effect of side grooves on the stress state around the crack tip are discussed on specimens about 30% side-grooved in U, V and slit types comparing with a regular flat s

A novel method for measuring plane stress dynamic fracture toughness was presented by Xia et al. 48 17-24 (1994)]. A formula for calculating dynamic J-integral (J\*) from the measured average load-displacement behavior was introduced by extending the quasi-static deep crack formula proposed by Rice
A B S T R A C T A three-dimensional, time-dependent computer program is used for the stress-strain analysis of elastic-plastic materials subjected to tensile loads. Several geometries are considered. The capabilities and advantages of this explicit finite difference computer program are demonstrated
