Hi, I am analysing a static structural model in Ansys Mechanical and am interested in the “Average” equivalent stress value across 2 bodies in the model.<\/p>\n

Could someone please enlighten me as to how this average is calculated?<\/strong> Is it an average across the total number of elements or total volume?<\/p>\n

I am wondering because I do not have a uniform mesh, there are mesh refinements in areas where higher stress is seen. If the average is done across the number of elements, I imagine that this will skew the result as there are a higher number of elements in the high stress regions.<\/p>\n

I have ran the model with a coarser, more uniform mesh and the average value decreased considerably (from 5.7 MPa to 4.6 MPa) but maintained relatively consistent max\/min values. <\/p>\n

Any information will be appreciated, thank you.<\/p>\n
