Could anyone please help on how to deactivate the crack propagation capability?
Following section 10.7.1 in the User Guide of 6.13, the crack propagation capability can be deactivated in some step. But I tried it in a very simple example through CAE and input file, it does not work.
I know the mechanics community have many codes to share. If you have developed engineering software including legacy Windows codes or linux codes, you can easily publish your code in the cloud and have it run on any devices including smart phones through cdmHUB.org. The codes could be simple codes you wrote for your dissertation or comprehensive commerical package like ABAQUS or ANSYS. You don't have to change your code, no source codes are needed. All you need to do is to upload your executable through a very straight forward way which only takes a few minutes.
I've been facing a very strange problem now when I'm using abaqus to finish RVE multiscaling simulation: so far, what I've done is successfully linking fortran and abaqus to run the whole calculation. At first, I met a small problem--- overwrite the old files(y/n)?---which has been solved by adding a "abaqus_v6.env" file whose content is as follows in the abaqus working direction:
I am a master student working on my master thesis using ABAQUS. I am modeling an experiment, but the problem is that my results from ABAQUS do not agree with the experimental results. Can you help me to check if I have done any mistakes?
Hi everyone... I've been working on a research study of Steel moment resisting frames. It includes finite element analysis of the frame in ANSYS apdl software. However, I'm facing a problem with the application of loads. The basic loading history for a single specimen testing program in the multiple step test in which loading history consists of stepwise increasing deformation cycles as shown in the attached file. In the basic loading history, the cycles shall be symmetric in peak deformations.
I need to apply the aforesaid type of loading on a particular nodes.
I was trying to create a load curve associated with time, such as a sine curve at the beginning, and then the force vanishes. Therefore, I cannot just use the periodic curve directly. I tried to input two loads periodic sine curves(same step) so that at a later time like t_0 the total load is cancelled. But it seems the displacement reaction is kind of weird. Is this the right way to do this kind of load-time curve, or is there another better way? Thanks a lot.
We are doing simulations of simple bilayer composites which undergo extensive buckling and post-buckling instabilities. The simulation is being done with ABAQUS explicit to capture the highly non-linear geometries. Everything works very well, however to compare with our analytical theory we need the Green strain at each element. ABAQUS for solid elements gives only the NE or LE which is projected onto the global coordinate system.
I want to update some nodal values of an existing Abaqus odb file using pyhton script. The problem is I don't know what kind of commands should I use in order to do this task?
Another question is how to delete an existing FieldOutput variable from odb file. I know by using add "addData" command, we can add user-defined field to the odb file, but how to delete an existing field output?
I worked with Direct Dynamic Analysis Method (DDAM) of the US Navy with Abaqus in 2007, but when I revisit it again in 6.14 version I didn't find it and it is not in the documentation also. Is it removed from Abaqus? and why? In ship building industry, they use it heavily till now.
Please, find the attached file about the method from a Simulia document in 2007
We're running two webinars in February on the latest additions to our software ScanIP's 3D image processing, visualisation and model generation capabilities. The webinars are ideal for existing users and those wanting to learn more about creating models from 3D images.
Introduction to the new ScanIP Animations Tool on February 11th (8am/5pm GMT)
The latest release of Simpleware’s 3D image processing and model generation software includes new features designed to enhance visualisation, analysis and segmentation of 3D image data. Features include a particles analyser, centreline tools and new physics modules for calculating effective material properties using homogenisation techniques.
I wanna get the dispersion relation of acoustic crystals in ABAQUS, so far as I know, the frequencies can be obtained by applying different wave vectors in the IBZ, but I dont know how to opperate in ABAQUS, in what way can we simulate the wave vectors (or the cooresponding wave length) . By applying force or displacement, or acceleration ?
Attacthed, should I model the whole structure or just the 1st BZ? If the 1st BZ is employed, should the periodic semmetric B.C. be considered in my model?
i have concrete slab and cfrp sheet i want to strength that slab with cfrp sheet so i try to model the epoxy layer as a cohesive layer between them the issue is when creating the orphan meshing which can be done by mesheing all instances as a normal mesh then selecting the slab and cfrp and go to mesh/creat mesh part after that go to mesh/edit and then selecting mesh/offset(creat solid layers) and now abaqus requires to select the element faces from which the offset will be generated so i selected the cfrp surafce that must be sticked to the slab by epoxy and then i create the set and assig
Hello my friends... I want to study ''fatigue crack growth'' in Abaqus...I need your help...Could anybody help me about this problem?? I need to know, what is the XFEM Abaqus out put for fracture mechanic??I meen does it give SIF,N(fatigue life) and the crack path??I read Abaqus documentation, it has said that Abaqus can do low cycle fatigue,Can I use it for HCF?? do I need to write a code or subroutine?? Thank you
