Description
Summary:Impact problems have always been of interest in the Aerospace industry because events such as "bird-strikes" occur quite often and necessary studies must be performed to observe the behavior of structures during the impact. This paper performs a study of an impact between a capsule filled with a liquid, modeled with SPH approach (Smoothed-Particle Hydrodynamics), and a rigid wall using the explicit nonlinear analysis. We also apply a rotation to the capsule to study how it affects different values such as impact pressures and structural stress. Another important aspect of this problem is the fluid-structure interaction and how different parameters influence the spill pattern of the fluid. We present some numerical results obtained for the above-mentioned cases.
