I am trying to estimate the stiffness from the oil inside a hydraulic system. For a simple piston it is possible to estimate the stiffness using two springs, which gives a total stiffness for the oil as: koil=E1A12/V1+E2A22/V2, where E is the bulk modulus of the oil, A the piston area and V the...

I have defined a plastic material in ABAQUS. Is it possible to visualize the stress-strain curve in ABAQUS?

Is it possible to view the beam orientation after it has already been assigned? I know the orientation is shown directly before a direction is assigned, but I would like to view it afterwards without reassigning the orientation.

I am doing a fatigue assessment of a structure under multiaxial loading. The load state for the structure is similar to the one in the picture below. Loads are presumed to be in phase. I am trying to obtain a stress range to estimate the fatigue life using the principal stresses of the FEA. I...

I am running a static analysis of a structure with multiple load steps. There are multiple contact definitions. In one of the load step, the structure deforms in a way such that a gap occurs between a contact pair. One of these surfaces is latter loaded, but since there is an initial gap the...

I am trying to compute the membrane and bending stresses using shell elements in ABAQUS. I would like to plot the resulting stress distributions. Is it possible to create a custom field output using the values at the top and bottom sections?

Is it possible to change the standard color of datums and reference points in ABAQUS? I want to switch from yellow to black.

I want to include ω in P_mag(ω) = m ω2e. Can I do this without using the amplitude feature?

I am trying to apply two loads which are frequency dependent in a steady state analysis. The forces are caused by a rotating unbalance: Fx=m ω2e sin(ωt), Fy=m ω2e cos(ωt), where, m is a mass, e the radius, t is time, and ω is the angular velocity. Is there a simple way to do this in ABAQUS?

That almost works! Using the getNormal() method returns the normal of the element. I need the normal to be positive in the surface direction. The getNormal() method does not give the right sign if the surface normal is opposite of the element. The positive normal direction is defined in the...

I have defined a surface in the CAE where one side is positive. I want to obtain the positive normal of this surface using Python scripting. Is it possible to do this in the visualization model using the OdbSet object? I do not manage to find anything in the documentation but it is possible to...
