Stress Analysis is a highly specialized field of mechanical or aerospace engineering. Stress analysis is all about structural analysis of different components on an aircraft. It involves sizing (for stress optimized dimensions) of components under various loads obtained from FEA and modeling, and then documenting all the analysis in the form of reports or stress notes. These reports are then later used for certification with the appropriate certifying authorities. For example, the Federal Aviation Administration (FAA) is the authority here in USA, European Aviation Safety Agency (EASA) in Europe etc., and wherever the aircraft is flying. Certification can be done by analysis or by static testing, it depends on the case.
