THE USEFULNESS OF IMAGINAL ELASTIC BOUNDARY: A Study on Application of MPS Method to Collision Problem between Tsunami Drifting Objects and Structures 1st report@@@津波漂流物と構造物の衝突問題へのMPS法の応用に関する研究 その1

The objective of present paper is to establish a unified numerical system using MPS method which can solve a series of the phenomenon from the occurrence of tsunami drifting objects until collision with the structures. In the present paper, the problems of the rational and practical simulation using the MPS method in collision problem between the structure and the tsunami drifting objects are solved by the imaginary elastic boundary. The validity of MPS method with imaginary elastic boundary in the case of applying to the collision problem is clarified by the numerical and tank experiments.
