Fatigue analysis of a cracked shaft : A finite element modeling approach

Shafts are typically used in sophisticated mechanisms and machinery which highly depend on shafts for rotatory motion which could lead to the failure. In today's contemporary, damages caused by cracking on mechanical components and structures have increased, causing crack and structural failure...
