Obtain the relationship of RULE OF MIXTURE of composites using simple force balance (2). Then
using this relation, compute the modulus of elasticity of a continuous and aligned glass
fiberreinforced composite consists of 40 vol% of glass fibers having a modulus of elasticity of 69
GPa and 60 vol% of a polyester resin that, when hardened, displays a modulus of 3.4 GPa (a) in
longitudinal direction (2) (b) transverse direction (2).
Question 8 (10 points, 5 points each) (1) A steel component is subjected to a reversed cyclic loading of 100 cycles/day over a period. of time in which ± 160 N/mm² is applied for 200 cycles, ± 140 N/mm2 is applied for 200 cycles and ± 100 N/mm2 is applied for 600 cycles. If the fatigue life of the material at each of these stress levels is 104, 105, and 2 x 105 cycles, respectively, estimate the life of the component using Miner's law. (2) An infinite steel plate has a fracture toughness of 3,320 N/mm³/2 and contains a 4 mm long crack. Calculate the maximum allowable design stress that could be applied around the boundary of the plate.
