In this video I take a look 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 nonzero stress components should be acting in the same plane.

Plane stress is particularly relevant for thin components which are loaded in a single plane.

In the video I look at three examples of plane stress a thin perforated plate, thinwalled pressure vessels, and thin gears.
