Stress Tensor

Non-Scalar Mechanical

The stress tensor {\boldsymbol {\sigma }} 1 is a Physical property. It is a second-rank tensor, representable as a Matrix, which consists of nine components \sigma _{ij} that completely define the state of stress at a point inside a deformed material.

{\boldsymbol {\sigma }}=\left[{{\begin{matrix}\sigma _{{xx}}&\sigma _{{xy}}&\sigma _{{xz}}\\\sigma _{{yx}}&\sigma _{{yy}}&\sigma _{{yz}}\\\sigma _{{zx}}&\sigma _{{zy}}&\sigma _{{zz}}\\\end{matrix}}}\right]

The image below offers an explanation of the directions in which each shear and normal stress component expressed above acts upon, relative to a Cartesian coordinate system.
