Reply To: Strain calculation at Gauss point

[Aurojyoti Prusty]

Hi,

Is there a discrepancy in the location of gauss points or the stress results? Generally PRESOL gives unaveraged element results which are discontinuous across element boundaries. What you have done is you did some sort of stress averaging in Matlab. For simple models this works fine because there is not much variation in strain between gauss points, but as the geometry changes significantly, the displacement gradient changes fast and averaging strains over there gives little more error than simple geometry cases. Please compare averaged stresses in simple model in Matlab and Ansys. Hope this helps.

Thanks,
