Determine the shape of a DCB specimen if G is to remain constant with the growth of the crack. The specimen is loaded in the constant load mode. Determine the depth of the specimen beyond the crack tip if the thickness of specimen remains constant (B=30mm). The initial crack length is 50 mm; modulus of elasticity is 207 GPa and depth of each cantilever is 12 mm up to the initial crack length.
