Two post-doctoral positions are available in the lab of Sachin Velankar in the Dept. of Chemical Engineering at the University of Pittsburgh to conduct experimental research on the biomechanics of surface texturing in cephalopods (octopus or cuttlefish), and to devise reversibly-morphing surfaces.  These animals are famous for their camouflage abilities.  Like many other animals, cephalopods can change their color, but in addition, they can also change the texture of their skin by expressing protuberances or wrinkles.

How to model a composite plate in ANSYS?

Submitted by Hamid Keshavarzi on

 

Hi friends,

 

I'm going to model a composite plate in ansys but I have few information about it. I need to know the exact procedure of selecting material ID and attributing to lay-ups and also to mesh the domain.This is a 5 layer laminate to analyse uniaxial buckling. I would be thankful for providing me with your friendly notes. 

 

All the best,

ANSYS crack propagation(growth) under cycle load simulation.

I want to simulate the crack growth under cycle load through ANSYS

I have thought two way to simulate it, first way is cohesive model(debonding)

second way is remesh(rezone at certain load step), this way is important for me, since this method mapsolves the new mesh into the old mesh, so the plastic strain information near crack tip element could transfer to new mesh.

I need a example file(code-command file of ansys) or comment

nanocalorimetry

School of Engineering and Applied Sciences, Harvard University

The Harvard School of Engineering and Applied Sciences seeks highly qualified applicants for a post-doctoral research position in experimental mechanics.  The successful candidate will participate in a project to make ultra-high-temperature calorimetry measurements on nanoscale quantities of materials. This apparatus will be used to study phase transformations in complex ternary and quaternary materials systems.

Dear colleagues,

First time in iMechanica. As a presentation, I am a researcher interested in Fluids and Solids Mechanics. My approach to research involves an interplay between experimental, theoretical and numerical modeling techniques. My principal research areas might be categorized as: Fluid-Structure-Thermal Interaction, Aeroelasticity, Material Resistance, Rotating flows, Mechanical Instabilities.

room acoustic

Submitted by avicina on

Hi

If I have a 3d rectangular room,  and I want to model 1/2 of that room because of symmetry boundary condition. in acousticFEM problem, what is my symmetry boundary condition in symmetry plane?

 

I mean at seymmetry plane which kind of constraint I should apply on pressure of the sound wave?

 

thanks alot

Hi all,

1. A new version of Eigen (v 3.0 now) is out (on March 23, 2011), and it seems promising. First, a few links:

The main page for the project is here: [^]. The page for v.3.0 is here: [^]. It seems to be very fast: [^].
