Experimental and Numerical Study of Brass Specimens Subjected to High Rates of Loading During Perforation Tests and Heated Using High-Performance Thermal Chamber

Abstract

The paper describes the mechanical behavior of brass alloy under impact loading. The work is focused on perforation tests carried out at wide range of specimen temperatures. This has been obtained due to application of the specially designed thermal chamber to heat specimens before impact. Based on this experimental series, the ballistic properties of the material impacted by conical nose shape projectile are studied. The experimental investigations have been extended by numerical simulations using a general purpose software Abaqus/Explicit. The phenomenological constitutive relation has been checked coupled with a failure criterion. Finally, good correlation is reached between numerical and experimental results.
