Thank you so much! This is the first online resource in which polymers are explained clearly in their non-linear behavior (most of resources focus just on metals or hyperelastic polymers). What I understood is that - although a multilinear plastic model is based on metals theory - it can be used also to model polymers plasticity given that you account for strain-rate and temperature conditions in which your stress-strain curve has been measured. Is it correct?
Thank you sir. But I have promblem. When I define true stress- true strain graphs all points for plasticty in the material definition, the results of the springback are less than the experiment. However, if I define only the line where the plastic strain is 0 (the first line (yield point)) as you describe in the video, the spring-back estimation gets much closer to the experimental results. Is it a correct method to define only the line where the plastic strain is 0? Do you have any other suggestions to increase springback in terms of materia? I should point out that; the material is copper and I am using stress strain curves from other articles. Because the experiment I'm analyzing is not mine.
Hi sir, I have question when doing abaqus v bending restart analysis, the metal sheet plate return into straight plate after I release the punch, do you have any idea on how it happen?
Sir! if i want use this method to extract stress-strain data. the stress-strain data will not be simillare & there is a fault "the independent variable must be arranged in ascending order" wat should i do?
Hi Abaqus Acumen team, Can you please validate FEM for Hertzian Contact theory for a 3D contact situation ? Being a most prominent theory in contact mechanics field, I find very less tutorials are there for validation in FEM. Kindly give us an nice video tutorial for FE implementation of HERTZ CONTACT THEORY ?
Hello dear sir. Please, can you explain in one video, how to make a simulation where you use no-linear hadening kinematic. Please, if you can help me, i´ll thanks a lot.
Sir !! It works thank u very much :) When I used 1000points it works from the data experimental. I convert the data to table then I used it for abaqus ( I used GetData graph digitizer 2.26 to convert a data to table) I m really happy may god bless u :)

From where did you obtain 1000 points in engineering stress-strain curve? Great tutorial.

Hi, do you mind sending me your datasheet for the pc_abs please?

Can I ask you how to obtain isotropic properties from experimental cyclic data?

Sir have you any knowledge about how to provide slip property between steel reinforcement and concrete beam.
useful video! could you help me to draw curved steel plate girder by abaqus,please? i need it in my master degree

Hi Sir!! Thank u for the tuto :)
I have did all the steps but the data was random ?? Can u help please !!
Sir !! It works thank u very much :)
When I used 1000points it works from the data experimental.
I convert the data to table then I used it for abaqus ( I used GetData graph digitizer 2.26 to convert a data to table)
