Fifteen-Pass Presetting FEA Report for a D60 60Si2MnA Disc Spring

Curated summary

This report evaluates height and residual-field convergence during fifteen presetting passes on a D60 60Si2MnA disc spring. Free height decreases from 5.35 mm to about 4.9627 mm, with the first pass contributing roughly 69.9 percent of total settlement; the combined height and residual-field criterion identifies the first eight passes as most significant. The material model is a non-certified proxy, so the report supports process-trend assessment and still requires test calibration.
