Structural integrity refers to its capacity to resist a designed structural load without breaking down from fatigue, distortion, or fracture. Good maintenance practises are always the ultimate solution to the above issue. However, in the real industrial environment, many unforeseen circumstances occur. This may lead to unexpectedly, reduction of life-span of many components. Thus, there is a dire need to assess each case to avoid future failures and catastrophes. This is achieved through knowledge of material and structural integrity.
