i know why cant we consider volume instead of area
thanx

eng-tips forums is member supported.
one dimension is occupied by the direction of the stress. that leaves two dimensions (in other words, area).
hi veibll
thanx for ur response
  but if a load of 200kg applying on 1m*1m area,
let us take ,if i keep depth 0.01mm,wht will be the result
   & also in other case if i keep depth 100mm ,what will
be the result,
i mean to say irrespective of area,depth will also take load,but in calculation part,depth is totally out of scene
my question is why cant we keep,..
               force/volume
thanx in before

stress, by definition, is a planar entity. if you want to look at stresses in a part at varying locations ("depths" as you put it), you look at different cross sections, depending on what it is you are interested in. force/volume is weight density.
hi freinds
thanx to all for answering my question
well, my problem is solved using theory of failures
like principle stress theory,principle strain theory
thanx once again to all
