Finite Element Analysis To Determine Static And Dynamic Properties Of Al-Alloy-7075 By Sicp Composite Material

Abstract

E research hollow spheres of aluminum alloy A356 filled with silicon carbide (sichs) for quasi-static (3/10 image -1) And high strain rate (up to 1520 s -1properties) pressure. This vehicle closed cell foam, called The syntactic foam, are of interest in structural weight sensitive applications. This work focuses on Understanding the mechanism of pressure failure and link them with the microstructure of the material. The He found himself on the strengths and syntactic foam pressure plateau 163 and 110 sichs be MPa, respectively. measured properties are much higher than the aluminum matrix fly ash filling existing CenosphereThe syntactic foam. failure mechanisms studio A356 pressure / sichs syntactic foam and direct evidence It is obtained from an overwhelming hollow sphere at the end of the flexible areas.Forecasts compressive strength Obtained from the current model is validated with experimental results. A thorough analysis of data open and closed cell foams complete that contain a porous gas and syntactic foam. There is a clear advantage in terms of reduced observed high elasticity limit and the A356 / syntactic foam sichs compared with another foam density. yield point aluminum foam in different strain rates at high pressure can be compared with the semi-fixed values, but most The foam is strong evidence of the sensitivity of the compression ratio in the high speed system does not appear deformation
