Abaqus: How can I fix the center of a gear? - Please Help!!

Submitted by zeke2282 on

Hi,

I´m trying to simulate the contact between two gears. Each gear has 60 triangular tooth and all of them are in contact at the same time. 

I have one external gear and one internal gear. The internal gear is driven by a torque applied at it center. 

I know that I should fix the center of the gear but I don´t know how to do it with Abaqus. Ive started to use two weeks ago.`I´ve already done the tutorials and reading the Manual!.

Please Help me!!

 



Best wishes

Thermo-mechanical model of friction stir welding

Submitted by Aurelio on

My name is Aurelio Tronci and I am a PhD student at the University of Cagliari (Italy). My research topics are related to friction stir welding (FSW). The work done so far has focused on the application of the DOE technique in order to investigate the influence of welding parameters on the microstructural and mechanical properties of aluminum alloys (AA 2198 T3-T8) joints. At the moment I am interested in the development of a thermo-mechanical model of FSW with CFD, but I find it really difficult to find material constants (Sellars and Tegart law) for all the alloys I have to test.

Static Load in ABAQUS Explicit

Submitted by MitsosOSougias on

Hello,

I have to do a simulation with two loads, a constant static load and a dynamic load that rapidly decreases. What is the best way to handle this? Should I create two steps one for the static load and one for the dynamic load and let the static load propagate, or should I just have one step where the static loas acts instantly and the dynamic follows an aplitude?

The problem with the two step idea is that when I create the static load as static, I cannot get the choice of Dynamic/Explicit on the creation of the next step.

Any ideas

Pressure load definition in ABAQUS when the surface is constantly changing

Submitted by Mukund Gupta on

I am new to abaqus. I am trying to simulate a simple model in abaqus- an elastic spherical shell being sucked into a rigid tube. the diameter to the shelll is thrice that of the tube and I want to study the large deformation of the shell into the tube.

moving heat sourse (laser) in ansys

Submitted by ostwals on

hi everybody ,

i m quite new wd the ansys ,and was trying to simulate a problem of moving heat sourse  (laser )

laser is having a gaussian beam distribution and has to move wd some velocity over a face of the plate .how could i model heat distribution of the laser and how coulad i move it wd some velocity.. 

i hope i m clear,plz help me out. 

Post-Doc Positions in Computational Materials / Computational Chemistry at The University of Texas at Arlington

We are seeking two post-doctoral researchers to pursue computational studies of polymer-derived high-temperature ceramics, which exhibit an unusual structure at the nano-scale. Projects involve quantum and classical molecular dynamics simulations, modeling structure formation and fracture mechanics, solid state and gas-solid thermodynamic processes, and oxidation behavior.
