    Application of loading and unloading in Abaqus

    Your load is time-dependent therefore use dynamic,implicit step type. You may apply this load with tabular data; Create boundary condition in load module. But when selecting step in boundary condition, choose your first step name. Don't select "initial" step. If you select initial step...

    stent wire / expansion surface contact problems

    I think there may be something like that; In the model which you followed, I think there may be a modelling tecnique like that; 1- Analist may have modelled the shell and wire with the clearance between them. 2- The clearence equals the half of the shell thickness. (I suppose that he defined...

    Excluding Peak Stresses From FEA Results

    I agree with TGS4 about the assessment of the quality of the question. I confronted with the same problem a few times. My opinion is the same with victorpbr. Some FEM programs (I use Abaqus) stress linearization tools classify the stress types. This may help you...

    stent wire / expansion surface contact problems

    Hi ryan, I think, at the first photo, your blue part is shell and green part is beam. (Is that true?) Are you expecting your blue part (which is shell) be interact with your green part's imaginary outer surface (which is beam)? I don't think it is possible for the beam sections. I suppose...

    Abaqus deflection control problem | job successful | but no bending | zero result

    I basicly investigated your model. You are pulling the reference point through U2 direction but there is not any connection between your reference point and Part-2(cylinderycal part) in the same direction (U2) direction. Therefore your RP-1 is only sliding in the space and so non of load is...
