oil at more than 30 munitions sites across the United States is contaminated with explosives. The U.S. military has discovered that the composting process, and the use of finished (mature, cured) compost can effectively remediate munitions-contaminated soils. To incorporate such soil into the composting process, the soil is excavated and mixed with other feedstocks. The end-product is a contami...

Shaped-charge penetration of explosives is studied analytically and experimentally. Two models are developed, each applicable to a different regime of jet velocity. The first addresses high-velocity penetration. If a jet is sufficiently fast, its penetration velocity will exceed the explosive's detonation velocity, and the process may achieve a steady state with the crater following the detonat...

Bending process is one of the most significant fields of application of sheet metal die. In bending process, it is quite vital that the product should have the desired angle. Furthermore, in order to obtain the desired angle in the bent parts, spring-go and spring-back amounts must be known. In this study, 30o, 60o and 90o bending processes were applied to S235JR (1.0038) sheet metal having 3, ...

Fluid-explosive rocks of the dike complex are identified in Middle Timan. The have convergent properties due to a combination explosive and metasomatic processes. study petrographic features revealed their nature. Further chemical composition rock-forming minerals established source mantle material paragenetic relationship with carbonatite magmatism. fluid-explosive dyke long-term multistage fo...

Abstract The theoretical analysis and numerical simulation are combined to explore the generation mechanism propagation characteristics of shock wave in WEIF process. results show that with increase linear density deposition energy, distance same time is longer; as increases, velocity on front gradually decreases. In early stage electric explosion metal wire, shape generated expansion evolution...

slab method of analysis has been used for solving metal forming problems for a long time. however it has been restricted to plane strain and axisymmetric problems due to limitations in its formulations. in this paper a new formulation has been proposed so that it could be applied to three dimensional problems in metal forming. a parametric slab has been considered in this analysis and the force...
