Functions

S1(p, Re, R0)
S2(p, Re, R0)
S3(p, Re, R0)
cycle(p, R0, thickness_init, Syield, Sultimate)	cycle to find a thickness that satisfies the von Mises criteria
getPeakStresses(p, Re, R0[, proof_factor, ...])
iterate_thickness(p, R0, thickness_in, ...)	apply the wall thickness adjustment factor, return it w/ new thickness
wallThicknessAdjustmentFactor(p, Re, R0, ...)	get factor by which to increase thickness when von Mises stresses exceed material yield safety margins
