NOTES
·
On
-ve face, -ve direction, stress component is positive
·
There is
a gradient of of stress component from –ve to +ve face.
Stress field is continuously varying.
Note that center of cube is origin P
Let
be
the stress tensor at a point P. Let
be
the body force/volume at that point.
Note :
be
the body force/mass.
