Reanalysis for structural modifications in boundary-element responseand design sensitivity analysis

Abstract

A reanalysis technique is presented for obtaining changes in response variables due to changes in design parameters with the boundary-element method. The approach is considered for static response analysis and design sensitivity analysis. Two iterative schemes, one based on total quantities and another based on incremental quantities, are developed. Numerical results are obtained for analyses using: 1) single-zone discretization; 2) multizone discretization; and 3) multizone discretization with condensation
