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
I am using a steady-state dynamic analysis procedure to model harmonic loading of a structure. I am investigating different material definitions. When I applied transversely isotropic stiffness using engineering constants, I saw a much different response than expected. So, as a test, I compared the following two models which gave DIFFERENT results:
I am new to ABAQUS software and recently i was trying to implement compressible neo-Hookean material in ABAQUS and for me it is a very difficult task. There are already codes available for the nearly incompressible neo-Hookean material. Since ABAQUS is a widely used software, i was wondering whether there are any database avaible consisting different codes that we can access. I am desperately looking for a subroutine for compressible neo-Hookean material. Can someone please help me or give me some direction. Thanks a lot !
