Sensitivity Analysis: Nonlinear Static Spring Systems

  • Daniel A. Tortorelli
Part of the CISM International Centre for Mechanical Sciences book series (CISM, volume 511)


We now progress from the linear static spring system to nonlinear static spring systems. Again we discuss both the analysis and the sensitivity analysis of these systems with the anticipation of eventually solving optimization problems. And again we use the simplistic spring element because the goal of this chapter is development of the overall program structure. As is the case for the linear spring system, the spring element is rather simplistic, however the assembly and solution details are not. Please be sure to master the concepts in this chapter.
