Modeling shear strain using 3D part Modeling shear strain using 3D part tamoora1983 (Automotive) (OP) 7 Jul 18 05:27 First post so forgive me if it's a silly question, trying to model this simple loadcase but I am not getting the expected results. Here is what my results look like in Abaqus, what could I be doing wrong? Or in other words, how would you model this loadcase in Abaqus CAE?

RE: Modeling shear strain using 3D part tamoora1983 (Automotive) (OP) 7 Jul 18 17:55 Thanks Mustaine, so you think I need to go with a 3D model? How should I apply the force? Should I use the traction force with magnitude = 1000N / (0.2m *0.02m) ? I tried several things and I am not able to get close to the hand calculations [ delta_x = (F*h)/(A*Shear_modulus) = 1.67e-7 m ] RE: Modeling shear strain using 3D part Mustaine3 (Mechanical) 9 Jul 18 08:00 Yes, you can run it 2D. But here the same counts regarding Hourglassing. 2D would also eliminate the question how to apply the force.
