Abstract: A method for indirect measurement of vibration stress of thin cylindrical shell (TCS) was proposed in this study. Firstly, TCS's vibration stress and response under different base excitation ...

Abstract: Accurate calculation of natural frequencies is significant for accurate prediction and suppression of motor vibration and noise. In order to reduce the errors caused by simplified structure ...

Detonation and fragmentation of ductile cylindrical metal shells is a complicated physical phenomenon of material and structural fracture under a high strain rate and high-speed impact. In this ...

Explosively formed projectile (EFP) warheads use the principle of energy accumulation to crush the charge cover through the detonation of the explosive, and make it turn over and deform to produce a ...
