(b) A [(0°)2/ +20°/-20°/90°), carbon-fibre reinforced PPS laminate is subjected to the following applied stresses: oxx = 300 MPa; Oyy = 250 MPa; oxy = 100 MPa; Given the ply properties below, calculate the values of normal strain in the global X and Y directions, and in-plane shear strain in the laminate. Given: EL = 95 GPa; ET = 10 GPa; GLT = 3.5 GPa; VLT = 0.32. where the E, and Et are the modulii in the longitudinal and transverse directions, respectively, Glt is the shear modulus of the ply and ylt is the Poisson's ratio of the ply.
