Webdistribution over time due to creep. This results in an increased probability of failure via creep rupture when the two distributions overlap. Figure 6: Graphical representation of the apparent reduction in strength over time associated with creep in a constant stress condition. In cases involving static strain, the concept and the failure WebFatigue failure is when the surface of a material begins to crack or fracture, causing the part to weaken. Typically, the first stage of fatigue failure is crack initiation. Crack initiation occurs once applied stress exceeds tensile strength. The next stage that occurs is crack growth. When a crack has been initiated, it continues to grow ...
