Abstract: An analysis based on elastic rod theory is given for the early-time axisymmetric response of pointed penetrators. Results of measurements by laser interferometry of the back surface particle ...

Abstract: A model is developed to estimate the force on a conical-nosed penetrator for normal entry into geological targets that have linear hydrostats and fail according to a Mohr-Coulomb criterion with ...

Abstract: Approximate solutions are developed for one-dimensional pulse propagation in a medium with an analytic wave speed when the ratio ε of the pulse length to a characteristic length of the wave ...

Abstract: A model to predict the forces on conical-nosed penetrators for normal impact into dry rock targets is developed. The target medium is described by a linear hydrostat, a linear shear failure-pressure ...

Abstract: The response of a string to a mass particle undergoing a constant horizontal acceleration from rest has been calculated. The string deflection is expressed in terms of the transverse mass ...
