{wiki=Piola–Kirchhoff_stress_tensors}
The Piola-Kirchhoff stress tensors are mathematical constructs used in the field of continuum mechanics to describe the state of stress in a deformable body. They provide a way to relate the stresses in a material to its deformation, capturing both the current configuration and the reference (or undeformed) configuration of the material.
