Plane Stress

Definition - What does Plane Stress mean?

Plane stress is a type of load that is applied to a material. Plane stress deals solely with the loads that occur in parallel to the plane being considered. Plane stress does not involve any forces that are applied perpendicular to the plane.

Understanding plane stress is important to avoid material failure.

Corrosionpedia explains Plane Stress

While there are many different forms of stresses and loads that can be applied to a material, plane stresses are among the most commonly encountered. As a result, plane stresses are often calculated when analyzing stresses that a structure or component may be subjected to.

One particular application where plane stresses are especially relevant is in applications with thin, flat structures or parts. A common object that requires a thorough plane stress evaluation is a bracket.
