jännityksenmuodonmuutos
Jännityksenmuodonmuutos, sometimes translated as stress-strain transformation, refers to the process of calculating how stress and strain components change when a coordinate system is rotated. In mechanics of materials and solid mechanics, stress and strain are typically represented by tensors, which are mathematical objects that describe these quantities in a specific orientation. When a material is subjected to loads, the internal forces (stress) and resulting deformations (strain) create stress and strain tensors.
However, the components of these tensors are dependent on the chosen coordinate system. If we rotate the
The transformation equations are derived using principles of tensor algebra. For stress, the transformation involves rotating
