Abstract: Dynamic snap-through criteria are compared for an impulsively loaded shallow circular arch modeled as a Kelvin-Voigt material. The Budinasky-Roth criterion is used in conjunction with direct ...

Abstract: This paper demonstrates the capability to perform three-dimensional computations for explosive-metal interaction problems with complex sliding surfaces. An analysis is performed for an explosive ...

Abstract: A numerical method of synthesizing motion considering the dynamics of a system of n degrees of freedom which is applicable to either a linear or nonlinear system is presented. The technique ...

Abstract: Methods of summarizing and presenting freight car truck load data obtained on service tests are described. Data from four separate test programs are presented in various formats. The data show ...

Abstract: This paper presents an analysis of a copper torsion test specimen exhibiting a thermal softening instability at a high strain rate. A consititutive relationship derived from test data includes ...

Abstract: A Lagrangian analysis technique is presented for two-dimensional axi-symmetric impact problems involving elastic-plastic flow. This technique is based on a triangular finite-element formulation rather ...

Abstract: A three-dimensional analysis is presented for high velocity impact problems. A Lagrangian finite-element technique is formulated for tetrahedron elements subjected to large strains and displacements. ...

Abstract: The special case of horizontal wave forces on large vertical cylinders in deep water is considered. The typical application for such a case is the calculation of horizontal forces on column ...
