2. Previous impact experiment A full-scale experiment of aircraft impact on a concrete panel was performed by Sandia National Laboratories (SNL) in The primary interest of this experiment was to reveal uncertainties in analytical methods and to evaluate impact force time hist ories against the aircraft impact on a rigid target. included development of basic design models, fiber or section based analysis, and detailed continuum based models. No experiments were included in this initial study, but observations from prior experimental research were to be used to support the work. The goals of this preliminary study were to develop initial answers to uncertainly in the.

The Pershing II was a nuclear-armed Intermediate Range Ballistic Missile deployed by NATO in to counter the SS Saber IRBM fielded by the USSR in A two-stage, solid-fueled missile, the Pershing II could deliver a variable-yield 5 to 50 kiloton warhead to a target up to 1, miles away. The warhead was precision-guided by on-board active radar using internal radar maps, with an.

must address the effects of wind-driven missile impact on storage tank structural integrity and inventory security. This paper describes one such evaluation for two condensate storage tanks (CSTs) and associated piping connections at an East Coast U.S. nuclear power plant (Plant). The impact of a wind-driven missile.   Ejection Force. The ejection force of the missile is provided by the launcher, which is simulated by unidirectional force with body in ADAM. Its magnitude is F(t) = P(t) x S, (2) where P(t) is the experiment measurements of gas pressure at each time, as shown in Figure 3; S is the effective area at the bottom of the missile.

The terminology used when describing local missile impact effects was clarified and the empirical formulae commonly used to predict the local missile impact effects were summarized. This and other research suggested that seven phenomena are associated with missile impact effects on concrete targets, as shown in Fig.

1, by: The finite element representation of the missile impact on the reinforced concrete wall is shown in Figure 4. The missile is prescribed an initial velocity of m/s, corresponding to the measured impact velocity in the experiment. Two of the ends of the concrete wall are enclosed by two U-plates (Figure 4) that span the entire.

This paper describes a series of missile impact tests of reinforced concrete slabs. The primary objective was to investigate the local behavior of slabs. The method of testing consists of making steel missiles collide against reinforced concrete slabs.

A total of 12 tests were performed varying the targets and missile conditions. The evaluated existing empirical penetration models did not predict the behaviour of the model scaled hardened buried target penetrators in concrete structures with acceptable accuracy.

One of the empirical penetration models was modified to better describe the performance of these penetrators in concrete protective structures.

Impact of Solid Missiles on Concrete Barriers. Semianalytical formulas are developed to predict scabbing and perforation thicknesses for reinforced concrete panels subjected to impacts by solid steel missiles. The scabbing thickness is defined as the thickness that is just enough to prevent the peeling off of the back face of the panel opposite to the face of impact; perforation thickness is.
