Abstract
En 中文
This paper deals with the development of a discretization strategy that minimizes the total computing time for solving shape optimization problems in linearly elastic systems. It employs a combination of boundary elements for integration of the governing differential equations and a first-order optimization algorithm. The proposed optimal discretization strategy is implemented and tested using a representative example problem and its effectiveness is assessed in comparison to alternative strategies.
