Today's ammunition still consists of about 70 wt% structure-providing materials such as metals providing no energetic contribution. Therefore, reactive structure (RSMs) offer tremendous room for improvement. While current research focuses on rather heavy, metal-based (e. g., alloys, thermites), polymers appear an under-recognized opportunity very lightweight RSMs. Unfortunately, suitable are un...

Abstract This paper is majorly discussing the impact resistance of hierarchical lightweight lattice structure. Firstly, unit cells pyramidal structure and traditional single-stage hollow are designed. At same time, concept relative density introduced to better demonstrate In this paper, ABAQUS/Explicit software used simulate drop hammer simulation The result shows that than Meanwhile, samples p...

Understanding metadata written in natural language is a premise to successful automated integration of large scale, language-rich, classifications such as the ones used in digital libraries. We analyze the natural language labels within classification by exploring their syntactic structure, we then show how this structure can be used to detect patterns of language that can be processed by a lig...

The article describes the results of theoretical and experimental studies to identify relationship between parameters steam structure thermal conductivity ashclaydite. correlation dependences coefficient ash-claydite on its stream have been established. analysis these works shows that lightweight concrete depends type porous aggregate, direction heat flow in relation layering concrete, average ...

Structural lightweight concrete (SLWC) has superior properties that allow the optimization of super tall structure systems for the process of design. Because of the limited supply of lightweight aggregates in Korea, the development of structural lightweight concrete without lightweight aggregates is needed. The physical and mechanical properties of specimens that were cast using normal coarse a...
