Hi everyone,
I have to model a composite steel-reinforced concrete shear wall with steell encased profiles . I searched in the literature and I found that for concrete is used SOLID65 element, and for reinforcement and steel encased profile is used LINK8 -3D spar element. I defined this 2 elements and two materials for them, BISO and CREEP(implicit creep).
I have a problem in my research that involves a platinum electrode which will form bubbles of hydrogen gas. Bubbles sticking to the electrode is expected to be a problem, and one method of dealing with this is to induce resonant vibrations in the electrode. These vibrations can be excited by running an alternating current through the electrode, which produces physical forces through electromagnetic interactions.
This is a great problem. Getting the boundary conditions right is going to be a real challenge. They should be able to be implmented as slip on the free boundary, possibly as a weak form contribution. Instead of posting an article, I have attached a document about this sort of problem in 2D from a model implemented in Comsol Multiphysics. This document provides some basic analysis of the problem, and may be of some use here.
Hi, dear friends,
I am new to i-mechanica and working for a reaserch institute for steam and Gas turbine in Aachen,Germany. I am doing Modal analysis of a Gas turbine matrix burner and want to find out the diffrent mode shapes and the frequency. My problem is, I want to impose a temperature field of round about 1800°C which I will extract from CFD results. SO I would be grateful if any one can tell me how can I impose temperature field to get this modes and frequency because this things are influenced by temperature.
Have a nice day
Hi everyone,
I am used to use 'dstran, stran, drot...' to develop my user subroutine UMAT and VUMAT codes in Abaqus. But recently I read some publications in which they use dfgrd0, dfgrd1 and dtime to develop their codes. I want to know what are the differences between these two ways?
Thank you very much!

Dear All
I am studying on thermal stresses analysis, however I have a problem here and need helps.

Hi everyone!
I need advice, I have to carry out a bridge-truck interaction analysis in ABAQUS FOR CATIA. I don´t know where I can start, the thing is that now I´m going to try doing it, in a simplified model in order to don´t loose time.
Can you help me? Can you give me some advices? how to model de truck? I need more or less precission on the bridge not in the truck. I know how to modelice the bridge, the type of element, the meshing, the connectors... but what I don´t know is how to manage Explicit,
Hello everyone,
I am coding a VUMAT for Abaqus/Explicit. I was wondering if the tensor components ordering was ALWAYS different from the one used in ABAQUS/Implicit, or if the special ordering was valid only for the C3D8R element.
Hello.
I'm attempting to model a thin composite laminate plate in ansys and after searching this website and using the ansys help, I have chosen to use shell 99. However when I load up the Ansys 8.0 software on the university computers (I am a student), I can not seem to find the Shell 99 choice, or in fact any of the other possibilites, such as shell 91, shell181, solid 46, or solid 191.
Just wondering if anyone would know why this is the case, I'm hoping that it;'s not because it's a university edition or something.
