![]() ![]() Top of Page Hydrodynamic Ram Numerical Simulations of Ram GunīlazeTech has been producing numerical simulations of hydrodynamic ram using LS-DYNA software. See sample deformation below for the detonation of a charge placed at the left of the tank center height. Our engineering model accounts for inertia, the liquid head, and a non-uniform blast and calculates the deformation, strain, stress, and failure. The ratio of height to diameter of such containers is of order unity so that a classical bending model does not apply. We have developed fast-running engineering models for failures under blast loading of liquid-filled cylindrical containers as found in an industrial facility. In the picture below, failure occurred at the seam. Failures occur when the maximum principal stress reaches material strength. Tanker Impacting a Rigid Wall Tank Failure Due to Pressure Loading Internal LoadingīlazeTech has developed fast-running engineering models to predict failures in tank subjected to internal pressure. We have also developed our own 3D codes for these problems, such as our improved modification of the Smoothed Particle Hydrodynamics method (SPH) to simulate impact problems. #HYDRODYNAMIC RAM PRESSURE EFFECT SOFTWARE#We also have many years of experience using commercial software including LS-DYNA, ABAQUS, and CTH to handle cases with more complex geometry and complex loadings. We have developed fast-running engineering models for these types of problems. BlazeTech specializes in structural dynamics and failures under a variety of loadings. ![]()
