feszültségtenzor
The feszültségtenzor, or stress tensor in English, is a mathematical object in physics and engineering that describes the state of stress within a material. It is a second-order tensor, meaning it has nine components arranged in a 3x3 matrix. These components represent the forces acting on infinitesimal surfaces within the material.
The stress tensor is typically denoted by the symbol $\sigma$. In a 3D Cartesian coordinate system, the
In many situations, the stress tensor is symmetric, meaning $\sigma_{xy} = \sigma_{yx}$, $\sigma_{xz} = \sigma_{zx}$, and $\sigma_{yz} = \sigma_{zy}$.
The stress tensor is a fundamental concept in continuum mechanics and is used in various fields, including
