planestressSituation
planestressSituation is a term used in continuum mechanics to describe a plane-stress state in thin structures. It applies when a body’s thickness is small relative to its other dimensions, so stresses normal to the plane are negligible. This simplification is widely used for sheets, films, and thin plates under in-plane loading.
In planestressSituation, the in-plane stress components sigma_xx, sigma_yy, and tau_xy can be nonzero, while all out-of-plane
Limitations: The assumption holds for thin structures subjected primarily to in-plane forces. It breaks down for
Applications: sheet metal forming, thin-film mechanics, MEMS devices, and structural components where in-plane loads dominate. It
