Coupled Numerical Model for Residual Liquefaction With Partial Dynamic Approach
The evaluation of the seabed liquefaction is one of the key factors for the design of foundation of marine infrastructures. In this paper, a new numerical model developed within the framework of OpenFOAMĀ® is proposed by two new features: (1) coupling oscillatory and residual mechanisms; and (2) adop...
