A procedure is developed for identifying the forces on the nose of a penetrator vehicle from strain time histories at selected points in the vehicle in off-normal impact of the vehicle. The vehicle nose is idealized as a rigid body, the remainder as a deformable rod. The following forces are considered: axial forces, transverse forces in two planes, and bending moments. The deformation response of the vehicle is assumed to be linear. The identification is separated into the identification of the flexural forces and axial forces. (Author)
