I am working with a simulation of a thin component bonded to a thick
component in ABAQUS 6.7. Here I utilize beam (B21) elements bonded to
plane strain elements (CPE4R) using a *TIE constraint, and another
simulation that uses plane stress elements (CPS4R) bonded to plane
strain elements (CPE4R) using a *TIE constraint. In both cases the
plane strain elements represent the slave surface for the bonded
I am having some troubles with the extrude command in Abaqus cae. I have modeled my sample as a 2-D geometry and now I want to move to 3-D for the same section. But I am having trouble extruding my 2-D section. It seems to me very weird and far to complicated the extrusion process in abaqus for such a simple task...
Herewith I announce to you that we created a discussion forum for topics related to our contact mechanics software on our website www.kalkersoftware.org .
The idea is to facilitate discussions and information exchange between users,
and between users and developers.
Am writing as a statement in my model the option initial conditions, am not sure where is the excat palce so i run my file to identify the error "as follows" but still not knowing where to do so?!! (it said under level: Model)!!!
is it possible to load (or simple harmonic ...) this structure to make it resonates and see the amplified strains.
What are the steps:
- I have already started extracting the natural frequencies (modal analysis I took 6 modes).
- I still have to apply a harmonic load F (t) = f 0 cos (alpha * t), I can not make this charge (I froze here)
- Instead it will force following the direction of the first response of the structure (the first nature-value) in the direction of the distortion along the + y axis (blue arrow)
I'm doing project entitled, " Study on the behaviour of CFRP strengthened concrete structures subject to cyclic loading" both experimental and analytical part using Abaqus. ( All dimensions are in terms of SI units[N,mm,s])
concrete dimensions: 1500 x 100 x 200 (L x B x D), M40 grade,
Abstract:The braking operation is a process which converts the kinetic energy and the potential energy of the vehicle into other energies. The major part of the mechanical energy is transformed into heat. ¶During the braking phase, the frictional heat generated at the interface disc - pads can lead to high temperatures.
I've modeled a composite sandwitch with ANSYS with a pressure. The element chosen was SHELL181.
I want to know the Stresses in the x, y and xy directions; the displacements and the deformations only in a few points so as to compare with the Navier and Rayleigh-Ritz solutions made following Reddy's book.
1.-The first problem is that I don't know how to ask ANSYS to list the displacements and deformations.
2.-The second one is that I know how to ask ANSYS to list all the elements in a layer,
hi how r u im doing a project based on landing gear struts system . i want to replace hydralic landing gear system by spring damper system in ls dyna . plz guys i need urgent help i m short ov time plzzz help me out
Last year when I started implementing interface elements to model material failure, I realized that the formulation is easy except how to generate a mesh with interface elements. I did a googling to search for such a free program. Amazingly, I did not find any although there are many researchers working on the fracture mechanics field.
So, I wrote a small object-oriented C++ program which reads a FE mesh, duplicates nodes and insert interface elements where asked. The program is able to
(1) insert 1D/2D interface elements everywhere in a FE mesh
Has anyone ever used a vumat subroutine with Eulerian elements? it seems that the stress update formulation is different from the way it is in Lagrangian approach! If you have any experience in this regard I'd highly appreciate if you share it with me.
hello i am in my first contact with abaqus i worked with plaxis but i want to model a pile in cyclic load i think that abaqus is more complete than plaxis but can any body show me how to start using abaqus in geotechnical problem
I would like to combine Extended Finite Element Method (XFEM) with cohesive behavior in Abaqus to model bulk damage as well as interlaminar damage in a material.
Section 10.6.1 of the Abaqus 6.9 Analysis Users Manual says that XFEM "can be simultaneously used with the surface-based cohesive behavior approach or the Virtual Crack Closure Technique, which are best suited for modeling interfacial delamination."
Hi, i need help modeling sandwich structure in ANSYS 12.1, i have found some materials online on how to do it? I have tried the basic steps. got some results, but now how do i validate that. I have experimental data for three point bending. But i want to make sure that what i am doing in ANSYS APDL is darn right.
3 layers 45/0/45
thickness 0.1/0.365748/0.1 (inch)
material i am using right now are carbon fiber and foam DH100
properties of each layer have been assumed to be isotropic
