What is the approximate yield strength of 250 maraging steel at room temperature? (No need to do a 0.2% offset, just estimate from the graph)
Qu2. (A) What is fatigue? Mention the sequence of steps involved in fatigue of a smooth specimen. Mention Four (4) factors that affect fatigue of smooth specimens, stating how each affects fatigue life (B) A very wide panel made of a material of plane-strain fracture toughness of Kic=55MPaVm was found to have a central crack of size 2.5mm. It is subjected to cyclic loading at a design (or working) stress of 690MPA and stress ratio of zero.
