Dear all, I am doing the gear contact anlysis and want to get the bending stress in abaqus to compare with the Lewis Theory, but I do not know which variable is suitable for the description of the bending stress in the gear tooth root? S11? S22? Max Principal? Mises? Any suggestions will be...

Hi helmi30. I am not sure but I think you can try like this: 1. You can output the loading-time graph since the loading is input by yourself. 2. You can output the displacement-time graph in the visulization module. 3. From Create XY data, there's an item called 'operate on XY data',you can use...

Hi, I am not sure but would you follow assembly-constraint-merge/cut see whether it's useful? Or a tie interaction will be the alternative method probably. Ju

Totally agree with 2nd floor. And the rigid surface should be the master surface.

I got it thanks very much

Thanks johnhors. An element stiffness matrix has many general characteristics that can be used to check the formulation of a particular stiffness matrix. An element stiffness matrix must have the following properties: Symmetric - This means that kij = kji. This is always the case when the...

Thanks akaBarten I think you are right. However, it's probably for a stiffness matrix to be sparse. why there's no zero element in the matrix? I tried another cases and no zero appears either.

hey guys! i use the *element matrix output KEYWORDS to output the element stiffness matrix. the result displays: ---- ** ** ELEMENT NUMBER 1 STEP NUMBER 1 INCREMENT NUMBER 1 ** ELEMENT TYPE C3D8R *USER ELEMENT, NODES= 8, LINEAR ** ELEMENT NODES **...
