aluminum storage tanks pressure imposed membrane stress

What is a Bending Stress? - Definition from Corrosionpedia

aluminum storage tanks pressure imposed membrane stress#0183;Bending stress is the normal stress that an object encounters when it is subjected to a large load at a particular point that causes the object to bend and become fatigued.Bending stress occurs when operating industrial equipment and in concrete and metallic structures when they are subjected to a tensile load.Thin-walled Pressure Vessels MATHalinoA tank or pipe carrying a fluid or gas under a pressure is subjected to tensile forces,which resist bursting,developed across longitudinal and transverse sections.TANGENTIAL STRESS, t (Circumferential Stress) Consider the tank shown being subjected to an internal pressure p.The length of the tank is L and the wall thickness is t.Structural Analysis Software for Silos and Storage Tanks Customer Projects of Silos Storage Tanks.Industrial Filter Device,Germany.The project for designing a filter/dryer device including agitator required a complete stress and deformation analysis in RFEM.A special design challenge represented the complex modeling of the structue having 1,424 surfaces,158 solids and 425 members.
