derivative of stress
Hi, I have got the stress distribution of a structure, shown in attached Fig. 1. I want to calculate the derivative of stress along y, namely, d(solid.mises,y). But the results I got are zero, shown in...

Hi, Try using d(solid.mises,Y) instead. The Solid Mechanics interface is formulated on the material frame, so you need to take derivatives with respect to the material coordinates (X,Y,Z) rather than...

Hi Henrik, Thanks so much for your helpful answer. I tried d(solid.mises,Y), and it works. Now I got the stress gradient along y axis, shown in attached Fig.3. I want ask it is possible to calculate...

In the 'Results' node, 'Derived Values' subnode, you can put a surface integral.

Hi Pieter, Thanks for your answer. For my calculation, surface integral is different from summation. Because the units of summation and integral are N/m3, N/m, respectively. What I want to do is...

You can integrate and then divide by the total surface area (or the other way around). Summation I do not know. What points would you choose for the summation?
