Abstract:

Based on the stress field formula near the crack tip，double-sided V-notch component models with initial cracks were established．The effects of notch depth，crack length，opening angle，material parameters and other factors on the notch stress field were quantified．A simple formula for solving the stress intensity factor SIF of the double-sided V-notch component with initial cracks was derived，which could be used for rapid prediction of the stress field and SIF of the notched component with cracks．The comparison results show that the error between the simplified formula and the theoretical method and finite element simulation results is relatively small， which verifies the effectiveness and accuracy of the improved formula．

Key words: composite, anisotropic plate, initial crack, notch stress field, stress intensity factor
