    How to apply elasto-plastic material property in first step and elastic property in the second step?

    Hi FEA way, I have tried to import the first step that was elastoplastic, to the current abaqus file using pre-defined field in loads. Now when I am trying to change the material property to elastic, it says "One or more instances of the current part are associated with an Initial State...

    How to apply elasto-plastic material property in first step and elastic property in the second step?

    Thank you FEA way. Will import functionality allow changing the material property from elasto-plastic to elastic? In my case, I want to use elasto-plastic in the first step to allow forming. In the next step, I want to give pressure and displacement to the formed component giving elastic properties.

    How to apply elasto-plastic material property in first step and elastic property in the second step?

    Hi, I have an axi-spymmetric model. I want to apply elasto-plastic material properties in the first step and elastic material property in the second step. Is there a way to do it? What I did is, while defining the material properties, I have given the plastic properties only at 20 degrees and...

    Ratcheting in Abaqus

    Hi I am doing Ratcheting of a pipe bend in Abaqus. I have cyclic stress-strain curve data. I have given the data as shown in the attachment. But what hardening should I select and should I give any suboptions? I have no other data other than the cyclic curve. To my knowledge, the cyclic curve...

    How to do elasto-plastic analysis in Abaqus

    Hi, I want to give half-cyclic curve properties of a material to get the plastic behavior of the component during cyclic loading. I have the values of stresses and strains as shown below 0 0 25 0.010973478 50 0.022751482 75 0.036091362 100 0.051730571 125 0.070394475 150 0.092799677 175...

    How to get a stress-strain curve from Abaqus simulation?

    Thank you FEA way, I have plotted S22 vs E22, and got a beautiful hysteresis curve. Thank you.

    "Too many attempts made for this increment" error

    You can try increasing the number of increments or you can reduce the min value or increment size in Step.

    How to get a stress-strain curve from Abaqus simulation?

    Hi, I modeled a pipe bend, pressurized it, and gave a displacement. I want to plot the stress-strain curve for the maximum stress location. It is an elastic-perfectly plastic model, so I have plastic strain as well. To plot the stress-strain curve, I have taken the von-mises stress and (Emax...

    How to add creep subroutine in Abaqus?

    Hi, I am new to creep analysis in Abaqus. I understand that I need to go to materials->plasticity->creep->select user subroutine. What should I do after that? 1. How to write a subroutine? 2. If I have a file where a subroutine is written, where should I upload in Abaqus Standard? Thanks in...
