Simulate a thin-wall aluminum container filled with fluid impacting a solid barrier. Compute the reactive forces on impact and compare with experimental measurements.
Calibrate and test the SPH methodology of LS-Dyna simulating fluid/structure interaction.
Propelled by compressed air, a can of liquid is shot at the instrumented target at approximately 80 m/sec. The can ruptures, spreading the fluid. Impact forces are measured by instrumentation of the target barrier.
The problem is set up using LS-Dyna and modeling the liquid with SPH elements. The can is modeled as a cylinder, the target is modeled as in the experimental setup. The problem size is approximately 146,000 nodes, and the total computing time was 99 hours on a dual-opteron workstation for a simulation time of 0.011 sec.
