Abstract Ultrahigh molecular weight polyethylene (UHMWPE) fiber orthogonally laid laminate is widely used in ballistic protection due to its excellent properties. Research on response under bullet impact meaningful for understanding the antiballistic mechanism and designing personal protection. In this article, three‐dimensional digital image correlation measurement analysis method applied study of UHMWPE laminates pistol bullets. A corresponding smoothed particle hydrodynamics (SPH)–finite...
The flow and dynamic recrystallization (DRX) behaviour of the Cu-0.19Cr-0.1Ag alloy was systematically investigated by hot compression tests using a thermal simulation testing machine. results showed that recovery partial occured at strain rate 10 s−1 in entire temperature range tested, rates varying between 0.01 below 850 °C. Complete when deformation higher than 900 maximum softening (ε*) variable Z were introduced DRX kinetic model developed for alloy, obtaining an Avrami constant 1.88.
This paper introduces a novel type of floating machine gun that can be simplified as self-balancing two-degree-of-freedom mechanical system with distinct vibration characteristics. The model accounts for intricate motion patterns and encompasses numerous potential influencing factors. Multifactor combination optimization the represents pressing engineering challenge. After establishing simulation validating it experimentally, seven factors were chosen variables. maximum recoil displacement...
Floating technology is an emerging firearm recoil reduction technique. Firearms utilizing this differ significantly from traditional systems, featuring distinctive characteristics of a two-degree-of-freedom system. This paper presents novel model for floating principle machine gun, incorporating bi-directional buffer spring. The established and validated against experimental results. experiment reveals both the body automaton exhibit quasi-harmonic motion with some randomness. An observed...
