Numerical simulation of stress-strain state near crack tip in a compact tensile specimen

A computational scheme has been developed and a numerical simulation of the stress-strain state near the crack tip is performed at different levels of the stress intensity factor using a compact tensile specimen as an example. The authors analyze the influence of the finite element size near the crack tip and compare the results obtained in different codes (software packages) for different crack geometries. __________ Translated from Problemy Prochnosti, No. 1, pp. 134–140, January–February, 2009.
