In summary, the concept of plane stress involves changing the perspective of viewing stress by rotating the view, which results in a change in stress values. This is due to the nature of Mohr's circle, where different angles on the circle represent different stresses. In real-life scenarios, this can be seen when pulling steel on a tensile machine, as it will shear at a maximum angle of 45 degrees. This is a result of the material's inherent properties and the way forces act on it.

Plane stress is a state of stress in which the stress components acting on a material are restricted to a single plane, while the stress components acting perpendicular to this plane are assumed to be zero. This is often seen in thin structures, such as plates or sheets.

The physical reason behind plane stress is the assumption that the thickness of a thin structure is much smaller than its other dimensions. This allows for the simplification of stress analysis, as the stress components in the direction perpendicular to the plane can be neglected.

Plane stress and plane strain are two different states of stress in a material. Plane stress occurs when the stress components acting perpendicular to a plane are assumed to be zero, while plane strain occurs when the strain components perpendicular to a plane are assumed to be zero. In other words, plane stress is a case of two-dimensional stress, while plane strain is a case of two-dimensional strain.

Plane stress analysis is commonly used in the design and analysis of thin structures, such as plates, shells, and beams. It is also used in the aerospace industry for the design of aircraft wings and fuselages, as well as in the automotive industry for the design of car bodies.

Plane stress analysis is typically done using the principles of solid mechanics, such as equations of equilibrium and compatibility, along with constitutive equations that relate stress and strain. Finite element analysis is also commonly used for more complex structures. In addition, experimental techniques, such as photoelasticity, can be used to visualize and analyze plane stress in a material.
