  Creation and propagation of crack is unwanted. It occurred because of a lot of things for example periodic force on specimen, elongation due welding, defect and hole due casting, thermal stress and so on. Although changing a part of structure is time consuming and need more money, finding a method to repair is very useful. For example in aerospace engineering and metal structure study repair of crack is very important that it has been studied for long time with kind of method.In this first represent kind of prevent of crack and restoration crack. After that report best method for each category (metal, plastics and …). Manuscript profile
