ABSTRACT

Stress analysis is a branch of mechanics dealing with evaluating the stresses

developed in a part subjected to mechanical forces. It has important applications

in engineering design, as well as in failure analysis investigations. By means of

stress analysis, the designer can evaluate the stress pattern developed by applied

mechanical forces. On the basis of this evaluation, proper materials with specific

mechanical properties can be selected so that the product can safely function

during service. In relation to failure analysis investigations, it is possible to evalu-

ate the stresses in the failed component at the time of failure. A comparison of

these stresses with the allowable or design stress provides important clues

about the possible causes of failure.
