Sensitivity Analysis in Structural and Multidisciplinary Problems

This entry is an introduction to sensitivity analysis and some applications in different topics related to continuum mechanics. Two main approaches, the direct method and the adjoint system one, are presented for both discrete and continuous design parameters. The theoretical investigation is supported by some illustrative examples in order to make more clear the analysis. Some notes on second-order sensitivity analysis are also included.
Many continuous systems are characterized by parameters, the values of which deeply affect their resulting mechanical behaviors under different conditions. Therefore, in a smart design procedure, it is very important to fix these values in order to fit a certain desired behavior or at least to investigate what are the effects connected to these modifications. Such a study is called sensitivity analysis: One is considering some objective functions which refer...
