Tank Failure Due to Pressure Loading

Pressure internal to tank

BlazeTech has developed fast-running engineering models to predict failures in tank subjected to internal pressure. Failures occur when the maximum principal stress reaches material strength. In the picture below, failure occurred at the seam.

Pressure external to tank

We have developed fast-running engineering models for failures under blast loading of liquid-filled cylindrical containers as found in an industrial facility. The ratio of height to diameter of such containers is of order unity so that a classical bending model does not apply. Our engineering model accounts for inertia, the liquid head, and a non-uniform blast and calculates the deformation, strain, stress, and failure. See sample deformation below for the detonation of a charge placed at the left of the tank center height.
