Modeling contact in ABAqus
i am working on modeling hertzian contact (general and standard conact in abaqus). i want to know how to model contact between surfaces of my assembly. i modeled it but it gives me error saying that my regions in the model are not connected.
How should I go about? is contact modeling different than just constraining the surfaces ?
Micro-plate's deflection
Hello
I'v been searching for micro-plate's deflection formulas.
Please help me in finding relations
Thanks
Call for Papers on Abaqus FEA for 2011 SIMULIA Customer Conference
The 2011 SIMULIA Customer Conference (SCC) will be held May 16-19, 2011 in beautiful Barcelona, Spain. A city filled with world famous museums, historical sites, shopping, entertainment, and culinary delights.
We are pleased to invite you to join your colleagues and share your Abaqus FEA experience by submitting an abstract by November 8, 2010.
Abstracts are also being accepted for papers detailing the use of Isight for simulation process automation and design optimization.
Looking for a Phd. position in Computational Solid Mechanics and Materials.
I am a final year Master of Engineering student at Materials Engineering Department, Indian Institute of Science. I have done my Bachelor of Engineering in Mechanical Engg. from Bengal Engineering and Science University, West Bengal, India. Currently I am working on my ME project "Simulation and Validation of Roll-Separating force and Limiting Reduction in Cold Rolling", under Prof Vikram Jayaram, Materials Engg Dept. and Prof S.K.Biswas, Mechanical Engg. Dept, IISc., Bangalore. After completion (June, 2011) of my ME, I want to do Phd.
molecular dynamics
hi.
i need some information about molecular dynamics application in mechanics.
please help me.
acceleration load - wave speed deformation
I am trying to apply a horizontal (x-direction) acceleration force to the bottom surface of a column via a explicit dynamic analysis. Every time I try to run the program, I get an error what states that wave-speed deformation exceeds 1.0 in some of the elements. Since I’m not interested in the stress at the bottom of the column, rather the response of the column due to the g-load, should I make the bottom surface a rigid body (or surface if I can)? The DOF in the x direction is free to translate. Any tips on how to go about this problem would be appreciated.
The Nobel, Graphene and 20% Google
Only after learning that 2010 nobelists AK Geim and Novoselov* got the
inspiration for Graphene during a 20% time break from "ongoing"
lab research. Did I realize how important is to have a "scheduled" free mind
and open Lab environment.
Does your lab practice "crazy friday" experiments jam sessions like Dr. Geim Lab in Manchester?
Validation and benchmarking problems for 3D fluid simulation with free boundaries
I have a hard time finding problem sets for validation and benchmarking of methods and codes for 3d fluid simulation with free boundaries. Please guide me to (standardized) problem sets or key litterture that is a suitable starting point. If there are not many standardized tests I would like to initiate a dsicussion about what a good test collection should be. I understand that iMechanica is focused more on solid mechanics than fluid dynamics but the overlap is big.
