다국어 초록 (Multilingual Abstract)

The method of finite spheres is a kind of non-element method that overlaps spheres of a certain radius in the analysis area without the need to construct a complex grid. When solving the explicit dynamics equation using this MFS, the inverse of the global mass matrix needs to be found, but since the size of the global mass matrix is very large, high computational cost is required to find the inverse matrix. In this case, there is a method to obtain the inverse matrix in the local area instead of in the global area using the direct mass inverse matrix method. In this regard, we will find the appropriate direct mass inverse matrix method and parameters using a meta-heuristic algorithm. We evaluated the superiority of the solution by comparing the accuracy and operation speed of the solution with the existing method when the improved direct mass inverse matrix method is applied.
