A Fast Calculation Method for Sensitivity Analysis Using Matrix Decomposition Technique

A Fast Calculation Method for Sensitivity Analysis Using Matrix Decomposition Technique

The sensitivity reanalysis technique is an important tool for selecting the search direction in structural optimization design. Based on the decomposition perturbation of the flexibility matrix, a fast and exact structural displacement sensitivity reanalysis method is proposed in this work. For this...
