A kinked edge crack has been detected in a large plate which is to be loaded by a remote tensile stress o-85MPa (Mode I). In order to determine if this can be done without risk for fracture, a finite element analysis of the structure was performed and the strain energy release rate was determined to be G=23.83kN/m. Assume that LEFM (linear elastic fracture mechanics) can be used. Will the structure sustain the load? Data: Plane stress and linear elastic material with E=210GPa, v=0.3, Kic=65MN-m-³/2, a=100mm

During tensile testing, you forgot to measure the change in the longitudinal dimension of the sample. However, you have managed to measure change in the cross-sectional area with time. With this information alone, will you be able to estimate the true strain exhibited by the material at a given time t. How accurate would such estimation be?
