Stress on curved surface

In certain cases, the plane stress model can be used in the analysis of gently curved surfaces. For example, consider a thin-walled cylinder subjected to an axial compressive load uniformly distributed along its rim, and filled with a pressurized fluid. The internal pressure will generate a reactive hoop stress on the wall, a normal tensile stress directed perpendicular to the cylinder axis and tangential to its surface. The cylinder can be conceptually unrolled and analyzed as a flat thi… http://www-mdp.eng.cam.ac.uk/web/library/enginfo/aerothermal_dvd_only/aero/fprops/introvisc/node9.html

WebSurfaces and Curved Stress Fields A thrust line is the centre line of the resultant of the internal forces of an arch structure. Accordingly, a Curved Stress Field represents the resultants of the internal forces of a solid structural surface. The internal forces of a structural surface can be deduced from the stresses Webillustrated by Fig. 1, a tensile surface stress pulls in the surface and makes the curvature of a thin ﬁlm/ substrate system more concave; a compressive sur-face does the reverse. Experimental determinations of the surface stress are based on such curvature measurements. 2.2. Measurements of the interface stress
