Hydraulic Metal Shear Cut

How it's made

Source

a hydraulic ram loads a steel bar; filtered oil-flow noise and a quiet 84-110 Hz pump grow for 0.35-0.65 s, then collapse as the bar parts. No pneumatic exhaust or room reverb is added.

Fracture

9 irregular 7-30 ms noise tears accelerate into a 3 ms excitation and final snap; a 90-220 ms friction bed darkens after breakthrough, modelling deformation ahead of the blade.

Body

clamped steel modes near 410, 1045, 2190 and 3710 Hz scale with stock size; their T60 falls from 0.38 to 0.12 s. A damped 110-200 Hz machine frame adds weight beneath the crunch.

Envelope

flow fades in over 25 ms; crunch peaks before the snap at 0.45-0.75 s. A small blade-stop knock follows 65 ms later; all energy fades by 1.40 s, with a silent safety tail.

Variation

seeded noise, fracture timing, strength and modal detuning avoid exact repetition. Stock sets mass and tuning, stroke sets loading time, bite sets tearing, clamp damps ringing.

Presets

thin stock is fast and bright; heavy stock loads slowly with a low crunch; a worn blade tears unevenly; close clamping gives a compact, dry snap with little free-bar ringing.
