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.
