A 12-ply Kevlar/Epoxy composite beam with layup [0/90 / 0 ]s is loaded in 3-point bending, as shown in Figure Q4. The beam has a length, L of 100mm, a width, b of 25mm and a thickness, h of 3.6 mm. Given the following material properties, calculate the value of applied load (P) which will cause first-ply failure. Use the Maximum Stress failure criterion. = E 70.0 GPa, E2 8.2 GPa, G12 4.8 GPa, V12 = 0.28 X=1730 MPa, X = 992 MPa, X2 = 45 MPa, XC = 65 MPa X6=65 MPa [30] Applied load W A 12-ply Kevlar/Epoxy composite beam with layup [0/90 / 0 ]s is loaded in 3-point bending, as shown in Figure Q4.
