Hello, I need to use equation constraint to impose this equation on two nodes A and B: u(A) - u(B) = C C is a constant = deformation x L The problem is that i don't know in Abaqus how to include in the equation constraint the constant C, i know that the equation should be written u(A) - u(B)...

Hello everyone, I am having this error message when i am applying 'equation constraints' between two nodes: "1 nodes are missing degree of freedoms. The MPC/Equation/kinematic coupling constraints can not be formed. The nodes have been identified in node set ErrNodeMissingDofConstrDef". What...

Hello, I am sorry for disturbing you again, i want to use the option of equation constraint to do the periodicity in my kelvin cell, equations should be: 1)Ui1 - Ui2 = Ui1(ref) - Ui2(ref) with i=1,2,3 (Uij(ref) are displacements of conjuguate points) 2)Oi1 - Oi2 = 0 with i=1,2,3 (O is theta...

Sorry for being not clear, yes it is exactly this

Good morning everyone, I was wondering if there is a way to force two nodes to have the same displacements without giving them values of these displacements. I'm going to explain with more details: i am working on a cellular material (foam with open cells), so i've modelized one cell of it...

Thank you so much i'm going to check this

The problem is that S22 wasn't in the field output, I just found S11 and S12 I am using beam elements (B31)

Hello everybody, I am trying to have the results of S11, S22 and S12 for a model but the problem is that in the list of variables, I can only choose S11 and S12 but S22 doesn't appear. I've tried to see in the field output but i cannot find S22 so i can select it. Please if anyone knows what...

Hello, I'm doing in Abaqus a Kelvin cell. My problem is that to have the results of stresses S11 and S22 , it gives me the results in the global coordinate system of Abaqus (its x y z axis) . But I have created a new local x,y,z axis and I want to have S11 and S22 following these new axis and...
