Such analyses must generally be conducted using explicit integration procedures, large three- dimensional meshes and realistic non-linear behaviour of the materials involved they must also incorporate the appropriate bolt stresses, internal pressures and thermal conditions prior to impact. This procedure implies considerable time and expense and, at some point, carrying it out becomes inevitable In spite of this inevitability, it would be very convenient to have at hand faster and cheaper procedures, able to generate some information about flask impacts without having to conduct the full analyses.
