UNITIVE ANALYSIS SCHEMES ON PROBLEMS OF MULTIPLE MOVING BOUNDARIES WITH 3-D LIQUID-SOLID MULTIPLE NONLINEAR COUPLING FOR UPLIFT OF ANCHOREDLIQUID STORAGE TANKS

In the paper, 3-D analysis method with unitive schemes is set up, whic h is used to resolve the uplift with multiple moving boundaries and mu ltiple nonlinear coupling for anchored liquid storage tanks. hi it, an algorithm of quasi-harmonious finite elements for arbitrary quadrilat eral of thin plates and shells is built up to analyze the multiple cou pling problems of general thin plates and shells structures with three dimensions, the complementary equations for analyzing uplifting movin g boundary problems are deduced. The axial symmetry and presumption of beam type mode are not used. In it, an algorithm is put forward for a nalyzing the Navier-Stokes problems of unsteady, three-dimensional, an d viscous liquid with sloshing of moving boundary surfaces in large am plitude under ALE frame by scheme of time-split-steps to which linear potential theory is not applied. The algorithms can be used to analyze the solid-liquid multiple nonlinear coupling problems with 3-D moving boundary with friction in multiple places.
