Abstract: A steel bullet in the form of a right circular cylinder which strikes a 10-mil-thick plane lead target at 45 deg incidence and at 2700 fps acquires on its front surface a series of ...

Abstract: An integral method for computing turbulent boundary layers on rotating disks has been developed using a power law profile for the tangential velocity and a new model for the radial profile. ...

Abstract: The effects of hub ventilation on the flow structure between corotating disks enclosed in a stationary cylindrical shroud have been studied using quantitative flow visualization. The ventilation ...

Abstract: Many practical devices involve high-speed collapse of shells of circular cross section, In all of the devices the stability of the collapse motion is of interest and in some it is essential ...

Abstract: Common practice for evaluating the seismic performance of earth dams uses design ground motions selected to be consistent with a target design response spectrum, which are subsequently used in dynamic analyses that estimate ...

Abstract: When a load, for instance a heavy roller, moves slowly along the surface of a solid mass of soft material, a “hump” deformation is often observed to precede it. The process of formation ...

Abstract: Successful operation of many practical devices that involve high-speed implosion of shells of circular cross section requires a stable collapse motion. In this paper, the dynamic buckling of ...

Abstract: Rods impacting a rigid target at velocities sufficient to produce several percent axial strain are found to buckle plastically with a fairly reproducible wavelength. This phenomenon is investigated ...
