Hello Everyone,
I have been working on solving contact problems relating to fibrillar adhesives over the past 3 yrs of my PhD work. In the past, I used Comsol FEM to model contact interactions by implementing the Dugdale-Barenblatt traction separation law at the contact interface.
Hi all,
I'm trying to model a 2D cohesive layer with a zero-thickness in Abaqus (6.11.2)
The shape of the layer is a quarter circle.
When modelling this i first create a cohesive layer with a certain thickness.
I then convert the part of this cohesive layer to a orphan mesh, then edit the mesh, such that a zero thickness layer is created.
However when i want to submit the job i get the following error message:
European Commission' s JRC (Joint Research Centre) is organizing the 2nd workshop on physics based modeling of material properties and experimental observations in collaboration with TOBB University of Economics and Technology. The workshop will be held in Antalya/Turkey on 15-17 May 2013, and the special focus will be fracture and damage mechanics.
hi all,
I have some problems with contact elements in ANSYS.
My model is a cube of matrx containing two fibres with periodic boundary conditions. The interface between Matrix and Fibre is modeled with contact elements and cohesive zone law.
In 2-D everything works out just fine when bringing up displacement in x-direction. Here is a movie I made of the Contact Status over the loadsteps:
Dear sir
I am Ravi dalmeya doing Phd from Indian Institute of Technology,Kanpur (India). I am doing work on adhesive elastic wavy thin film. I have completed 2-D Hertzian contact between cylinder and elastic half space using Abaqus. Now i want to apply Dugdale-Barenblatt cohesive zone model outside the contact zone and i do not know how to apply Dugdale-Barenblatt cohesive zone model outside the contact zone.Can you give me some suggestion?
Thanking you
Ravi dalmeya
Hello, everyone!
Could you, please, help me with the following issue?
I’m trying to simulate a crack growth in an anisotropic media using cohesive zone model (CZM), and the results I get do not agree with my expectations, based on a common sense and simple estimations.
As I don’t yet feel myself on a safe ground with APDL, I make use of Ansys Mechanical, implementing command objects where needed.
Can anyone suggest some basic literature on Cohesive Zone Modeling and it's implementation through FEM? Most of the literature, I find, is on traction-separation behaviour and some simulation using a FEM package. I 'm interested to learn it's mathematical formulation and implementation through FEM. Can anyone help me?
Praveen.
