IRA assisted MMC-based topology optimization method
Kangjia Mo, Hu Wang, Zhenxing Cheng +1
An Iterative Reanalysis Approximation (IRA) is integrated with the Moving Morphable Components (MMCs) based topology optimization (IRA-MMC) in this study. Compared with other class…
How we can control the crack to propagate along the specified path feasibly?
Zhenxing Cheng, Hu Wang
A controllable crack propagation (CCP) strategy is suggested. It is well known that crack always leads the failure by crossing the critical domain in engineering structure. Therefo…
A novel X-FEM based fast computational method for crack propagation
Zhenxing Cheng, Hu Wang
This study suggests a fast computational method for crack propagation, which is based on the extended finite element method (X-FEM). It is well known that the X-FEM might be the mo…
A Meshless-based Local Reanalysis Method for Structural Analysis
Zhenxing Cheng, Hu Wang
This study presents a meshless-based local reanalysis (MLR) method. The purpose of this study is to extend reanalysis methods to the Kriging interpolation meshless method due to it…
