Abstract
Finite particle method (FPM) is introduced as a new approach to refined analysis of structures. Some efforts have been taken to extend the ability of FPM in refined analysis. The primary concepts and basic principles of FPM are briefly introduced. In spatial domain, consistent element coupling is implemented in FPM to balance the efficiency and accuracy, and a multi-scale planar truss is analyzed to demonstrate the robustness of the algorithm. In time domain, parallel acceleration for FPM on GPU is achieved based on the independence of solution process for each particle or element. The speedup ratio can reach up to 40~50x. A computer-aided design system for refined analysis of structures (RASCAD) is developed, which integrates a pre-processor, a post-processor and a numerical analysis module.
