One can now run GEBT (Geometrically Exact Beam Theory), a general-purpose nonlinear composite beam solver, online within a web browser through cdmHUB.org. Users do not have to install the code on their own machine. And users can access to immediate support if run into any questions. You are welcome to try out the code and let me know any of your questions.
We have a new case study on our website based on research at Imperial College into multiscale tomography and calculating permeability for catalysts. The project involved studying the influence of pore structure on fluid flow across large length scales in silica-alumina pellet-based catalysts.
3D data at different length scales was obtained from XMT, DBFIB-SEM and ET scanning and segmented into a binarised dataset.
I am trying to understand how Composite Layup works in ABAQUS. I have specified 5 integration points for each ply in the Composite Layup definition but I am getting the field output only at 2 integration points in every ply (the top and the bottom-most points). I do not understand this anamoly. Is there some additional definition that we need to give while defining the Layup so as to be able to see the field output (atleast stress) at all the integration points.
Any help would be appreciated. Thanks in advance :)
The Protuguese version of http://cadec-online.com/ is available. Previous versions include English, Spanish, and Farsi. English is the base version for the developement of the app. I did the Spanish translation. Farsi and Portuguese were done by volunters. We are looking for volunteers for other translations. pls contact me if interested.
In this case study, based on work carried out at Imperial College and University College London, research was carried out into the performance of solid oxide fuel cells (SOFCs). The microstructure of an SOFC electrode was obtained using FIB tomography, and a volume mesh generated in Simpleware software, with the model then exported to Abaqus CAE. Boundary conditions were set in the solver and stress analysis conducted, which were able to approxiamte peak maximum principal stresses in response to thermal expansion.
I finished my master in mechanical engineearing about eight month ago ... and in my Master career, I wrote a Fortran Finte element code with capabality of mortar cantact analysis[1,2] and rate independent plasticity with kinematic and isotropic hardening and with large deformation capabilty for isotropic materials[3,4]. My code converges very well and I achieved quadratic convergence and I didn't use any comercial Fe packages like ansys and abaqus .....
I have calculated the J-integral using ABAQUS for 5 contours but I could not find any information about the paths of the J-integral contours. Do you know how we can get the paths of the requested J-integral contours or equivalently how we can define the paths of contours in ABAQUS?
Hi. I'm working on multiscale modeling of soft tissues. I'm working
on modeling an orthotropic wavy fiber in WB. I write an APDL routine to
change the element coordinate system of each element with accordance to
the fiber curvature. Ansys documentation said that in the case of large
deflection analysis, the element coordinate system will be rotated with
accordance to element rigid body rotation. My problem is that, after the
solution, the elements coordinate system of some elements rotate
ble. Nevertheless cheap

to see how making use of solar mirror to provide energy might not be considered
an excellent remedy in regions in the region with several days of overcast skies
and inadequate sunlight. A bathroom mirror is an important accessories in every
bathroom. It is the one that make the bathroom look complete. Aside from its
functionality it serves as a decorative piece that can add beauty and depth for
the space. It can also make an illusion of space for a smaller bathroom. In
It’s with great pleasure that we announce the release of version 2.0 of FEBio (Finite Elements for Biomechanics). This new version can be downloaded here . FEBio is an open-source finite element package, specifically designed for solving problems in the field of computational biomechanics. This new version includes some major changes and contains a number of new and exciting features. Some of the noteworthy changes and additions are listed below.
I am trying to find out which was the first ABAQUS version, wchich includes the hyperfoam material model. I haven't found any version history about this. Could someone tell me the very first version of ABAQUS in which the hyperfoam model was included?
i want to know, is there any way to measure edge length ( "curves" specifically, not looking for straight edge length using distance between vertices as query feature :) ), and also to get vertices co-ordinates in local co-ordinate system; in ABAQUS CAE or using python scripting.
my problem is somehow related to above query, can manage solution with 'other' tricks, but want to know any standard methods are avaliable.
I've met some strange problems implementing umat. To speak in short, it's parallel degradation, which means when run in serial mode, everything is OK, there's no failure of equilibirium iteration and therefore no cut back, but when switch to parallel mode, there are random cut backs. I checked the process by outputing results to files and found very bizarre phenomenon, the data changes when transfering from the subroutine called to its caller. For example, if the main program calles sub(a), and in sub a is specified intent(out).
