plane stress การใช้

The multiaxial tensile test provides a plane stress boundary condition at the edges of the sample.
Plane stress typically occurs in thin flat plates that are acted upon only by load forces that are parallel to them.
In certain situations, a gently curved thin plate may also be assumed to have plane stress for the purpose of stress analysis.
It is important to recognize the fact that fracture parameter " K " c has different values when measured under plane stress and plane strain
One can still simplify the analysis by using a two-dimensional domain, but the plane stress tensor at each point must be complemented with bending terms.
