% Computes flywheel stresses.
The Tresca Stress must be less than the safe yield stress.
Type FlywheelStresses for a demo.
--------------------------------------------------------------------------
Form:
sigmaR,sigmaTheta,trescaStress] = FlywheelStresses( rho, mu,
omega, rO, rI, r )
--------------------------------------------------------------------------
------
Inputs
------
rho (1,1) Density (kg/m^3)
mu (1,1) Poisson's ratio
omega (1,1) Angular rate (rad/s)
rO (1,1) Outer radius (m)
rI (1,1) Inner radius (m)
r (1,:) Radial position (m)
-------
Outputs
-------
sigmaR (1,:) Radial stresses (N/m^2)
sigmaTheta (1,:) Circumferential stresses (N/m^2)
trescaStress (1,1) Tresca criteria (N/m^2)
