WebSo, for a point in the plane of bending, stress is given by S =KtT ±Kc C , where C is the curvature vector (Cx,Cy). Similarly, for a point at 90° to the plane of bending, stress is given by S=KtT. The stress factors will typically be calculated from experimental data or from detailed analytic models of the umbilical or riser cross section. There are experimental methods for measuring stress concentration factors including photoelastic stress analysis, thermoelastic stress analysis, brittle coatings or strain gauges. During the design phase, there are multiple approaches to estimating stress concentration factors. Several catalogs of stress concentration factors have been published.
