Workshop: Simulation Earthquake Load Over A Tank Contain Water And Investigate Sloshing Phenomenon In Abaqus

In this tutorial, an earthquake load is applied to a water-filled tank to study the sloshing phenomenon using Abaqus. Both the tank and the water are modeled as three-dimensional deformable parts. The concrete tank is defined with elastic–plastic material properties, while the water is modeled with viscosity using the Us–Up equation.

The earthquake load is introduced through a dynamic explicit step with a duration of 55 seconds. To capture the sloshing behavior of the water, a Lagrangian approach is implemented. During the simulation, the water begins to slosh, and the resulting waves collide with the tank walls, generating stresses in the structure.

Figures from the simulation are shown below.
