Thanks IceBreakerSour

Shall i copy the nodes also? Thanks IceBreakerSour

No. I do not. I just copied the Element. Thanks

I used this command in the input file to copy element set *Elcopy, old set = A, new set = B, Shift nodes = 10000, element shift = 10000 But i got this error message "The following elements in instance PART-1-1 reference one or more nodes that do not exist 10027, 10078, 10079, 10080, 10081...

Please read this post and the previous one, let me explain more. In the Global model, i am making Back-filling or rock material, so i change the properties of the intact rock with the properties of the back-filling. the back-filling is softer than the original intact rock. In my model i have...

Thanks Portliner for your help. Let me explain explain the Global model for you, the model is Three dimenions, i change the material properties of ten sets of the Global model in 10 steps, i.e., in each step i change the material properties of one set , i make these sets softer than before...

Please Read 23.1.1 in Abaqus user manual, specifically stress and strain measure. You will see how plastic strain is calculated from the true stress-strain curve.

I agree with you. And I really appreciate your help and your advice.May God help you and increase your knowledge since you are helping people.

Hello, I made a big Global model, and i want to focus on a small part of that Global mode by using Submodel technique. I notice that all sets generated in the Global model are not propagated to the Submodel when these sets are created in the Assembly module, and i got a generation failed...

Thank you iceBreakerSour. I got it

How can i copy set or a group of sets from the Assembly module to the part module. Thanks

Actually they are many, but the model is complex and re-generating the model from the begining is time consuming, how can that in the input file. Suppose the name of the set in the assembly module is set-1, how can i copy that set to the part module. Thanks

I made many partitions and sets in the assembly module, when i try to make submodel from global model which has all these sets and partitions, i found that all these partitions and sets which were generated in the assembly module could not be generated in the submodel. I notice that this problem...

Hello everyone, I using concreted damage plasticity criterion to simulate the damage of Rock. I have the stress-strain curve from both Uniaxial compression and uniaxial tension, i need to know how can i find the damage variables dt and dc. Thanks.

Hello, Your comments are highly appreciated. Thank you.

Hello Abaqus users, Can i use the Concreted Damage Plasticity to simulate the damage of Rock material such as Sandstone. Sandstone is a brittle material. and i read in the manual that Concrete damage plasticity is suitable for brittle and quasi brittle material. I will not introduce any kind...

Any body has any comment?

Hello I was calibrating a simple model (Uniaxial compression test). the model is just one element C3D8r. the model is elastic-perfect plastic. Please see the attached input file. i run the model two times. one time i used displacement control to apply load on the model, the second time i used...

Hello everyone I hope you are doing well. I want to use UFIELD or USDFLD subroutine to change the material properties of specified sets in my model at a specified step. In step 3, i want to change the material properties of set-1 In step 4, i want to change the material properties of set-2...
