Radial stress is based on Lamé's equation for a thick-walled cylinder using the following equation:
(1)
Here σr is radial stress, Ri and Ro are the effective internal and outer radii respectively, and Pi and Po are the internal and external pressures respectively. R is the radial position along the cross-section. You can request radial stress at the inner (Location=1) or outer (Location=2) surfaces. If you do not specify a location parameter, Flexcom computes the radial stress at the inner and outer surfaces, and outputs the larger of the two values. A positive value indicates a tensile/expansive stress, while a negative value indicates a compressive stress.
