I read the documentation.. So for the first equation constant can be automatically calculated in abaqus. (under half cyclic I will be defining my stress strain I got from uniaxial coupon test). But for the second equation isotro[ic hardening.. How i will get Q infinity and b values?? That i am...

Hi I am modelling a steel tube filled with concrete under cyclic loading. For concrete, I am using the Concrete damage plasticity model with damage parameters. and for steel, I am using the Kinematic hardening (KH) model. But with the KH model, I am getting weird results, which I cannot figure...

oh okay.. Creating a multiple part is only option then.. :( Thanks for the insight.

I want to select this face(marked as random lines) but at the location where i have created partition. https://files.engineering.com/getfile.aspx?folder=07927dbb-41e5-4e7d-a0ce-fb004e16a1ff&file=Capture.JPG

So thats the problem. I am not able to create surfaces. I created partition and after that when i am trying to create surface i am not able to select the surface i want.

I can share my model too. Maybe it will help in understand the issue i am facing. But i am not able to upload cae file here. Model has 3 parts. Its basically a composite columns with end steel plates. Its basically a steel tube filled with concrete.

Actually, for all contact, i have defined general contact with penalty friction as 0.3 and hard contact. but at partition I want to define contact with friction as 1 and hard contact. So for this i have define two interaction properties. So while defining contact at partition , I need to select...

I am trying to define a general contact interaction at a specific location in my model. To do that I was creating partition at the desired location but I am not able to select the surface after creating a partition. Can I do that?? or I have to create 2 part? creating two parts and then...

and also this gap won't be uniform. Somewhere it will be 2-3mm and somewhere it will be 0.1mm or less. so basically whatever space will be created in between steel n concrete i want to fill it with solid elements and assign air properties of conductance etc. and also I can not delete elements...

Thanks for your reply. i cant implement the suggestion you gave. please tried to explain the problem below. my problem statement is.. I will apply an axial load to the column. the column will deform/damage and a gap will be created. The next step is to Import the deformed geometry and create...

I am studying composite column (steel tube filled with concrete). so when I apply load on this column, the column will buckle locally and deformed globally. steel will debond from concrete and a small gap will be created. Now I want to model one interface between these two materials (gap...

So, I have installed everything again. And now verification is not completing. even after 30 min it will be stuck at the "check for parametric studies" .https://files.engineering.com/getfile.aspx?folder=b58f9482-4cb1-43b1-95dc-7afecdbbad70&file=verify.log

Yes I have the admin privileges to the system. Actually, FORTRAN compiler was already installed in the machine. so I installed VS 2015 and then ABAQUS.

another file.https://files.engineering.com/getfile.aspx?folder=190e5330-644a-47f9-883a-87dba96a9027&file=fortran_make.log

I have attached these two files herehttps://files.engineering.com/getfile.aspx?folder=b78e8d20-c6c0-41a8-9538-2d56017f046b&file=cpp_make.log

I have installed the Abaqus 2019 version and linked it with Visual Studio 2015 and Intel Parallel studio 2015 version to run the subroutine. After linking when I ran the verification it failed for ABAQUS make utility with FORTRAN and Abaqus make utility with C++. I have attached the verify.log...

Ok Thanks. My 5th step is thermal stress analysis. I am using sequentially coupled thermal stress analysis. So, In the 5th step I am already taking Nodal-Time temperature values in the predefined field by calling .odb file( obtain from heat transfer analysis). So if i create 2 separate models...

Thank you so much Mustaine3 and FEA way for your reply. I will try to implement your suggestion. So, (to be sure) I can't change the material model in between steps. There is no way except the suggestion you gave me? Right? not even any subroutine? I am asking because I was struggling from weeks...

I want to change my material model in-between step in a 5-step analysis. In the first 4 steps, I want to use Concrete damage plasticity model and in the last 5 step I want to use Concrete Drucker Prager model. Is it possible to do without using subroutine USDFLD file. Since I am not familiar...
