A special subset of pressures vessels are required to fully contain internal explosive blasts for commercial and government agencies conducting blast-related research and testing. In some cases these blast chambers must also safely contain the impact

The Los Alamos National Laboratory Dynamic Experimentation (DynEx) program is the designing and validating steel blast containment vessels using limited experiments coupled with computational models. Through a need to design portions of the vessel to

As part of the US stockpile stewardship program, it is necessary to perform experiments with various metallic components and explosives. These experiments will be conducted within specially designed blast vessels to ensure that the debris from the ex

This paper describes a formal similitude analysis for the problem of hypervelocity impact into shielded targets. The analysis indicates that the dissimilar material model approach can be used to investigate the response of prototype impact situations

During the 30-year lifetime of the Space Station, NASA is concerned that a large piece of orbital debris could strike one of the inhabited or laboratory modules. The modules are basically cylindrical pressure vessels, 4.3 meters in diameter and 9.1 m

Ballistic impact experiments were performed on ceramic laminate targets at three scale sizes, nominally 1 3 , 1 6 , and 1 12 , to quantify the effects of scale on various responses, in particular, the ballistic limit velocity. The experiments were ca

Velocity scaling is an experimental technique where substitute materials are employed to infer impact results for other materials at higher speeds. For example, impacts are conducted with cadmium at 5 km/s or zinc at 7.4 km/s to simulate the response

In the proceedings of the last symposium, recent work on a technique for launching small projectiles to hypervelocities above 10 km/s using an inhibited shaped charge was presented [1]. In the interim, experiments have been conducted using the inhibi

A hypervelocity fragment launcher based on an inhibited shaped charge was developed, which launches a 0.5–1.0 g aluminum fragment at 11.2±0.2 km/s . Experimental and computational work performed during its development are presented. The launched f

A computational study was performed to quantify the effects of strain rate on replica-model (scaled) experiments of penetration and perforation. The impact of a tungsten-alloy, long-rod projectile into an armor steel target at 1.5 km s−1 was invest
