STRESS VECTOR STRESS TENSOR STRAIN VECTOR STRAIN TENSOR

The stress (strain) vector is the components os stress (strain) written as a colunn vector. For a general three dimensional body this is a (6x1) matrix. The components of stress (strain) written in tensor form. For a general three dimensional body this forms a (3x3) matrix with the direct terms down the diagonal and the shear terms as the off-diagonals.
