The Efficient Engineer - Understanding Plane Stress 08072019

This video looks at "plane stress", an assumption used in solid mechanics to simplify the analysis of a component by turning a 3D problem into a 2D one. For a plane stress condition to be applicable, all of the non-zero stress components should be acting in the same plane. This video looks at 3 examples of plane stress - a thin perforated plate, thin-walled pressure vessels, and thin gears. Plane stress is particularly relevant for thin components which are loaded in a single plane.
