Respected ABAQUS USERS, As I have used C3D8R and all the structure is made using tie command by making a big thick plate with the strips and then attached by using tie in the interaction module otherwise if the structure is continuous by making grooves using the extrusion of the thick...
Respected ABAQUS Users, the analytical solution for this shows a big error in the output stress of 24% as when the grooves are made the enhanced area should give the peak value of force to 347 N as when the input nominal value of stress is 3.1 MPa which yields 347N peak while here the model give...
Respected ABAQUS Users, which filed output option is activated to get these output in the history output manager in the step module. As I just found CSTRESS and PPRESS but not CPRESS. I didnt find CSHEAR, COPEN, CSTATUS. Kindly guide me.
Thanks for cooperation
Respected ABAQUS Users, I have made two same cae abaqus cohesive zone model but just with a difference of surface to surface contact in one model and node to surface contact in another model gr8 and gr9 respectively in the interaction module and I got different results. Kindly solve this...
So may we use surface to surface with small sliding in abaqus standard for cohesive zone model. Is there an option if we use master and slave surface as a contact but use node to surface as a discretization method as selecting nodes is difficult sometimes may require python or other plugins. Thanks
Respected ABAQUS users, Also I want to request felling the newly modified platform a bit difficult to use as the best of my knowledge I uploaded 4 inp files for the assessment yesterday but here these files are not displayed as if these were attached or not and the time displayed for this...
Respected ABAQUS users, I would like to request the solution to the issue regarding making the contact in cohesive zone modelling.
1. When I used the node to surface contact in the interaction by selecting node as slave and surface as master in the discretization method the output results...
Alright thanks. Can you please shine light on my remaining questions regarding yielding and different slopes and the attached result file?
Thanks for cooperation
Respected ABAQUS Users, I want to ask about the experimental input for the cohesive zone modelling debonding of single lap joint during the shear test. Here I have an experimental input for some cohesive debonding force displacement curve and have several questions?
1. During the cohesive zone...
Even if it is not complete for the groove surface for time upto 0.14s even than the output is stable and not increasing and tending to decrease at peak of 1.2KN. The files are not modified and are same. Why this results shows less output reaction for groove case? The graph is almost bilinear and...
For that I have attached the output graphs for both of cases. The value for smooth peaks in negative direction just only because of the loading direction while for the rough surface is positive but the value of smooth is greater than rough as it is 2KN while for rough it just peaks at 1.2KN at...
I am measuring the reaction force at the reference point created where the load is applied. I think so it should work well as I measure the output for both smooth and grooved surfaces at the same point requesting filed output in the step module. Kindly assist.
Thanks
Respected ABAQUS Users, I am simulating cohesive zone modeling of with the input files attached here with one as a smooth surface and the other as a rough grooved surface. The output reaction force should be greater for the rough surface due to large area of contact. The model is developed using...
This file has big contact stress may be due to bending and the with the inclusion of crack tip.
How the output is processes to get the stress- displacement curve output ;how to selct element to get stress etc, of the debonding bilinear curve as the experimental input in this case is 27MPa as a...
Respected ABAQUS users, I am simulating the cohesive zone modeling by using cohesive contact rather than using cohesive elements but when I provide the initial notch or crack inside the model the mises stress goes very high as if the point of debonding is facing the extreme bending but most of...
Respected ABAQUS users, The output results of the 2d model of cohesive zone modelling of the double cantilever beam in abaqus documentation is bilinear. Is there an example of trilinear of trapezoidal output result? What parameter should be added to get trapezoidal output?
Thanks for cooperation
Respected ABAQUS users, I have tried to model cohesive zone model of two plates using some glue in ABAQUS but I am getting a high distortion node problem along with contact overclosure along with convergence issue may be due to incorrect modeling but on the youtube tuturiols I followed each and...
