laminate made of graphite/epoxy (T300/5208) is applied an in-plane torce = 400 [MPa*mm] and N=-300 [MPa*mm] h-0.2 mm, where x is along the 0-ply direction. The ply properties can be found in Table C.3. and C.4. (p. 466) in the textbook. (a) Plot the failure envelop under the maximum stress failure criterion (in o, and , space). Locate stress points for all plies. Would failure occur? If so, which ply will undergo the first ply failure? (Note: please ignore the effect from shear stress i.e. t,) (b) Plot the failure envelop under the maximum strain failure criterion (in o, and space). Locate stress points for all plies. Would failure occur? If so, which ply will undergo the first ply failure? (Note: please ignore the effect from shear stress i.e. t,,) (c) Plot the failure envelop under the Tsai-Wu failure criterion (in , and o, space). Locate stress points for all plies. Would failure occur? If so, which ply will undergo the first ply failure? (Note: please DO NOT ignore the effect from shear stress i.e. 1.- might end up having more than one curve) (Hint: "fimplicit" might be good option for plotting.)
