[Vo]:Question regarding basic solid mechanics and one directional applied stress

[David Jonsson]

Hi

If I put a wheight on a vertical cylinder it will be shortened and its
radius will be somewhat increased. I wonder if the radial increase is
considered a negative stress in radial direction?

Is the stress tensor something like this?

     -a  0  0
T=  0  0  0
      0  0  b

Where a and b are positive values and the coordinates are cylindrical *ρ*, *
φ*, *z* (ISO 31-11).
