Fractural Mechanics Crack Propagational Study on Different Material And Different Crack Location of weld joint in ANSYS
Abstract
Abstract
There have been spectacular failures made of ductile material. The structure as whole will remain as brittle only until the load is applied it will have elastic response it will not have plastic response. But near the crack tip there will have plastic zone and plastic zone indicates flow crack is going to behave for the present study analysis is carried out on crack near weld joint and three different material is chosen stainless steel structural steel and aluminum alloy. The observation of result is done from avg. value of SIFS, equivalent avg. stress v/s time and crack length v/s no of life cycle. From the result it is observed that for some crack length the no of life cycle of aluminum alloy is more than stainless and structural steel. On the other hand structural steel has more stress resistance to similar crack length.
