3. A flat plate 40-inch wide and 2-inch thick, which contains a through-thickness central crack of length 2a, is loaded in uniaxial tensile load of P = 3,000 kips. Plot K and S values on a strip yield failure assessment diagram (FAD) for various crack sizes. (Note: Variation of K,. and S,. is nonlinear with a). Estimate the critical crack size for failure. Given, yield stress ys = 50 ksi, OTS = 65 ksi, E = 30x103 ksi, KIC = 100 ksi Vin. 3.
