    Appllying bolt pretension load in Abaqus Explicit Solver

    Hello, Using a dynamic explicit solver in Abaqus, I am performing a post-buckling quasi-static analysis of thin-walled (2 mm thick) cold-formed steel C sections connected to a U section at both ends. As per my model geometry, the U-section is connected to hot rolled steel loading plates (12 mm...

    Abaqus error in in keyword *BOUNDARY

    Hello, I am doing a three-point bending analysis of a cold-formed steel beam. In the post-buckling analysis using the Abaqus explicit solver, I got the below error: in keyword *BOUNDARY, file "Job-18.inp", line 55500: Unknown assembly id 2 I have applied boundary conditions at the reference...

    What is in-plane stiffness of contact element and how to calculate that

    Hello, I am performing numerical simulations of the axial-compressive test of cold-formed steel-lipped channel sections (stud) connected to a small length of U sections (track) at both ends with self-tapping screws under axial-compressive loading (displacement-controlled loading along the...

    Query on contact pressure

    Hello, I am performing a compression test of a Cold-formed steel channel column connected to the track (U section ) at both ends. I use a softened contact formulation in Abaqus explicit for normal behavior (Scale factor: using general contact explicit). I am also checking so that there is no...

    Modeling soft contact with parabolic distribution in Abaqus

    Hello, I am simulating a compression test on a cold-formed steel-lipped channel column (stud). The column is connected with a small length of a U section (track) at the top and bottom. There is a gap between the stud and the track, and I have modeled the gap. Initially, I defined the normal...

    Query_modeling soft contact in Abaqus

    Hello, I am simulating a compression test of a cold-formed steel column connected to a small length of U sections at both ends with self-tapping screws. In the post-buckling analysis, I have defined contact conditions between the U section web and the top nodes of the column sections...

    Query about explicit solver

    09Hello, I am using the Abaqus explicit solver to conduct a post-buckling analysis of a cold-formed steel U section. The support and the loading points are made of 3D discrete rigid solid elements. The supports and the loading is applied through a reference point attached to the rigid body...

    Query about abaqus explicit analysis

    Hello, I am running a post-buckling analysis using the explicit solver. In the history output, I requested the top reference node's reaction force and displacement at every 0.001 sec. My query is: While the analysis is running, should I get the output at every 0.001 sec? Or is the output...

    Abaqus warning_zero force

    Hello, I am conducting a 3-point bending test of a cold-formed steel track section in Abaqus. First I did a linear buckling analysis. Following that I am doing a post-buckling analysis, taking scaled buckled mode shapes from the buckling analysis in the post-buckling analysis. The beam is...

    Query about Running Abaqus job in remote HPC system

    Hello, I am trying to run Abaqus in a remote HPC system. I have two jobs, job-1 and job-2. job-1 is linear buckling analysis First I ran job-1 in my HPC working directory and generated job1.odb (output) file. Now, to run job-2, it needs input from job-1.odb file.In the job-2.inp (input file)...

    Query on Abaqus Buckling analysis

    Hello, I am performing a 3-point bending analysis of a cold-formed steel U section in Abaqus. The end boundary conditions are pinned. The load applicator is modeled as a rigid plate. Initially, I want to perform a linear buckling analysis, to take scaled the buckled mode shapes into the...

    Restart analysis in Abaqus explicit

    Hello, I am running a post-buckling analysis of cold-formed steel stud and track assembly in Abaqus. Since the problem is highly nonlinear, I had to adopt the explicit solver. I kept the restart option on in my explicit step. Now, my analysis has been terminated because of some reason and I...

    Abaqus warning, max ratio parameter

    Hello, I am conducting a post-buckling analysis of a Cold-formed steel column in Abaqus. The column is connected to a small length of track sections at the top and bottom with screws. the track is connected to the loading plates and base support with 4 nos M8 bolts at the top and bottom. I have...

    creating contact surface

    Hello, I am trying to define the contact interaction between the bolt-hole surface and the bolt shank. The bolt-hole surface consists of three solid blocks. This is the master surface. When I am selecting three surfaces together: Abaqus is giving me a message that the selected regions must be...

    Sell element with solid extrude

    Hello, I am trying to model one bolted shear lab connection in cold-formed steel using Abaqus based on the literature. In order to accurately capture the localized bearing of the bolts against the cold-formed steel Guidance has been provided below: 'shell elements are employed for the modeling...

    creating bolt pretension load

    Hello, I am trying to create the bolt pretension load in the Abaqus explicit solver. Since, the bolt load, that is available in the static general solver is not available in the explicit solver, I am trying to create the bolt pretension using a temperature gradient(Based on guidance provided...

    query about S9R5 shell elements in explicit solver

    Hello, I am performing a post-buckling analysis of cold-formed steel studs and track section assembly. Since the solution is highly non-linear the implicit solver is not working for me and I had to adopt the explicit solver. For cold-formed steel, the S9R5 elements have some added advantages...

    Abaqus warning with connector elements

    Hello, I am performing the post-buckling analysis of a cold-formed steel stud and track assembly that are connected to each other by a self-tracking screw. In Abaqus, I modeled the screw stiffness using the connector elements. I have defined reference points on the stud and track surface, in...

    How to expedite dynamic implicit quasi static analysis

    Hello, I am performing a numerical simulation of the compression test of the cold-formed steel stud and track assembly. In a practical scenario, there is a small gap between the stud and track, due to the rounded corner. And the experimental curve has To simulate the gap closing behavior, I...
