This study characterizes the fractography of ferritic ductile iron under various loads, including tensile, fatigue and bending, and impact conditions. The results indicate that ductile fracture is the primary mechanism observed during tensile testing

A P≥k-factor of a graph G is a spanning subgraph of G whose components are paths of order at least k. We say that a graph G is P≥k-factor covered if for every edge e ∈ E(G), G admits a P≥k-factor that contains e; and we say that a graph G is

Let a and b be two positive integers with with $$1\le a\le b$$ and $$b\ge 2$$ , and let G be a graph of order $$n\ge \frac{(a+b-3)(2a+b-1)-a+1}{a}$$ . We say that G has all fractional [a, b]-factors if G has a fractional r-factor for any integer r wi

Orthogonal factorizations in graphs or networks have a wide range of applications in combinatorial design, network design, circuit layout, and so on. We investigate the problem on orthogonal factorizations in graphs or networks. Let G be a digraph. I
