The goal of failure analysis is to determine the causes that results in failure of a component.
By the failure causes determination it is possible in same cases to define the failure probability. For example, in order to predict the probability of failure, the imperfections of concrete components could be modelled as cracks with different shapes.
The kind of breakage and above all the exam of its origin made with specific instruments, allows to find the defects that can be the cause of the beginning of the breakage. Together with the above considerations, a careful exam of the surface brings to understand if the cause was the working conditions or the composition of the detail with defects.
Results of the analysis together with information on the working conditions find out the reason of the brakage and the failure probability. |
