material deposition to substrate simulation at ABAQUS

Hi;

I am trying to simulate material deposition to substrate. In our case material is added to substrate  and there is a distributed heat flux with constant velocity acting by node by node. I want to simulate showing the added material in the simulation and its effects. There is a command for that called Model Change in the ABAQUS. So is someone familiar to that kind of problem. And also I need to account mass diffusivity while the material is melting.

I will be gratefull for any advice you can spare

Best Thanks

Hello, I am Ravindra. I am working on cutting process simulations using ABAQUS software. I am getting some problems in preparing the input file. If anybody has the ".inp" file for cutting process simulation using ABAQUS, please send me. My email address is "aravindra321 [at] yahoo.com". It will be great help.

 

Best Regards,

Ravindra.

Experimental temperature field at the crack tip in a natural rubber

Dear colleagues, this is a paper on the experimental determination of temperature field at the crack tip in a natural rubber using a motion compensation technique. The contribution of the non-uniformity of the IR detectors and the Narcissus effect is taking into account to determine the temperature field.

crystallizable natural rubber

This is a study dealing with the volume variation in filled crystallizable natural (F-NR) and uncrystallizable styrene butadiene (F-SBR) rubbers subjected to cyclic loadings. During their deformation, such materials exhibit volume variation induced by the cavitation phenomenon and the decohesion between particles and the rubber matrix.

Next generation advances in energy storage for nanoelectronics, micro and nanosensors among others, require capacitors fabricated at the nanoscale. High dielectric constant materials such as ferroelectrics are important candidates for those. Consider the following: the expected capacitance of a 2.7 nm SrTiO3 thin film is 1600 fFmicro-m-2. What is the likely value in reality? 258 fFmicrom-2! This dramatic drop in capacitance is attributed to the so-called "dead layer" effect.

Volume variation in filled and unfilled natural rubber : competition between cavitation and stress-induced crystallization

Submitted by LECAM on
research
elastomer
volume variation
stress-induced crystallization
cavitation

this is a study on the competition between cavitation and stress-induced crystallization during the deformation of cis-1,4 polyisoprene rubber. During deformation, this kind of material exhibits volume variation induced by both phenomena. In this study, we propose to measure this volume variation by an original full-field measurement technique. The high resolution of this technique allows us to identify characteristic stretch ratios during mechanical cycles.

ABAQUS Bending moment diagram

Hi All

Can anybody let me know please, how to draw bending moment diagram using ABAQUS? I am fighting with this problem for a couple of days. I tried with the SF (SM1) variable but it does not give the value as I expected. Any help? Please.  Mahbub

The recent issue of Nature Materials includes a review paper on the deformation and failure of protein materials in physiologically extreme conditions and disease. The paper was interesting, so I am posting the abstract here. For the full-paper visit Nature Materials.
