In this study, displacement field around v-notches of a poly methyl metha crylate (PMMA) specimen with tip cracks will be analyzed using digital image correlation technique. First intensity factor in combination with in-plane rigid body translations and rotation components will be determined by linear least squares fitting of the displacement field data to the corresponding relations among stre...

An elastic-plastic model was developed to describe the deformation and permeability of fractured rocks under confining pressure. Elastic and elastic-plastic contact models were used in the model to analyze the deformations of a representative element containing a single fracture under various confining pressures. The present work utilized elements from contact mechanics and viscous flows to der...

• Hydrogen-induced softening of RPV steel with high DSA at 288 °C. Straining in DSA-regime induces plastic localisation and increased hydrogen-traps. HESIV HELP are dominant HE mechanisms active above-yielding post-necking stages, respectively. Fracture mechanics tests hydrogenated high-temperature water °C on low-alloy reactor pressure vessel dynamic strain aging (DSA) susceptibility revealed ...

Many composites fail by fracture events, such as fiber breaks or matrix cracks, rather than by continuous crack growth. Conventional fracture mechanics deals with predicting crack growth. This paper suggests that conventional fracture mechanics can be extended to predict fracture events by using finite fracture mechanics. In finite fracture mechanics, the next fracture event is assumed to occur...
