Abstract Wire-explosion impact forming (WEIF) is a process based on coupled effect of gaseous, liquid, and solid media, the experimental work alone not sufficient to properly show this complex process. To understand plastic deformation behavior workpiece under action shockwave load, WEIF AA5052 tubes were simulated in LS-DYNA by considering fluid/structure interactions. Then, stress, displaceme...

Experimental and magnetohydrodynamic numerical simulation results analysis of a μs- sub- μs-timescale overdamped underwater electrical explosion copper wires having different lengths diameters are presented. For these explosions, ∼80% the energy stored in pulse generator is deposited into wire during time comparable or shorter than quarter period underdamped discharge. It was found that thresho...

The liquid–vapor two-phase region has attracted the attention of various fundamental studies and applications. To explore region, underwater electrical wire explosion (UEWE) is a useful tool. In this work, we observe two different mechanisms transition in UEWE: volume vaporization spinodal decomposition. main factors through which occur are heating power pressure accumulation system during UEWE...

Electro-mechanical braking systems (see [9], References), also referred to as brake by-wire, replace conventional hydraulic braking systems with a completely “dry” electrical component system. This occurs by replacing conventional actuators with electric motor-driven units. This move to electronic control eliminates many of the manufacturing, maintenance, and environmental concerns associated w...

We performed molecular dynamics simulations of the high voltage pulse explosion single aluminum wires with energy ratio 0.6 in vacuum and studied role wire radial dimension. Simulation results show that large-diameter having a large material depth small specific surface can maintain higher deposition density effectively reduce influence difference thermodynamic parameters, leading to velocity l...
