Fundamental Study on Large Deformation Analysis of Composite Breakwater by Improved Elastoplastic MPS Method

Deformation analyses of rubble mound as an elastoplastic body have been already carried out, however, in these conventional analyses, large deformation to tilt a caisson on a mound cannot be reproduced. On the other hand, the MPS method used in this study can be applied for such a large deformation, however, in a conventional elastoplastic MPS method, an influence of pore water in a mound cannot be taken into account. Therefore, in this study, an improved elastoplastic MPS method based on effective stress model is developed, and a few fundamental examination of its validity are executed.
