When the layer angle of carbon fiber composite material is [+-15/90] s, please answer the following questions. But the physical properties of carbon fiber composite materials are as follows. E1=132GPa, E2=10.8GPa, v12=0.24, G12=5.65GPa, t_ply=0.135mm (a) Calculate the engineering constants EL, ET, vLT, and GLT for the laminate. (b) When the laminates are in a state of loading, calculate the deformation rate of the laminates. Nx=10000N/m Ny=10000N/m Nxy=3000N/m
