WebThe influence of gradients in hardness and elastic properties at interfaces of dissimilar materials in laminated metallic composites (LMCs) on fatigue crack propagation is investigated experimentally for three different LMC systems: Al/Al-LMCs with dissimilar yield stress and Al/Steel-LMCs as well as Al/Ti/Steel-LMCs with dissimilar yield stress and … WebWe will plug in some odd number for b and d, getting a/(2k) = b/(2m), k and m being some integer. because we are working with fractions, we need the denominators (b and d, or 2k and 2m) to be equal. Because k and m are not the same integer, we can multiply the two denominators together to get a common denominator, giving us (4km) as our denominator.
