Question

step by step solution please

1. Consider two materials- Aluminum and Steel. For each of these two materials, consider the surface energy term as follows: Y's=1 J/m2 and ys 2 J/m2. (a) If Aluminum and Steel have no defects of any kind, calculate their fracture strengths. (b) If each of the two materials, contain circular defects of widths 1um and 1mm, calculate their fracture strengths. Discuss the trends that you observe in the calculations for the fracture strengths. (If need be, you may have to look up literature sources for information about elastic moduli and lattice spacing information.)
