VABS 3.6 Reduces Realistic Composite Blade Modeling to Seconds

AnalySwift, LLC, a leading provider of efficient high-fidelity modeling software for aerospace and energy composites and other advanced materials, announced today the release of VABS 3.6. This is the latest version of VABS, which is the tool of choice for efficient and accurate modeling of composite slender structures such as wind turbine blades, helicopter rotor blades, high aspect ratio wings, composite bridges, and other slender structural components.

University Lectureship in Solid Mechanics and Materials Engineering, University of Oxford

The Department of Engineering and Balliol College at Oxford University have a University Lectureship available in the area of Solid Mechanics and Materials Engineering.  We would  be particularly interested in receiving applications in the general area of composite and lightweight materials, including, polymer, metal, ceramic, biological and multifunctional composites, foams and lattice materials. The closing date for applications is 16th January 2012.  Further information can be found in the attached files.

We look forward to receiving your application.

Industry-level journal about FEM applications

Hi dear mechanicians,

I am about to publish the results of my MSc thesis in a journal. The thing is, my project was carried out in industry about multi-scale FE simulation of impact in composites. So it is merely an industry-level application of available methods.

 I want to ask if any of you have any particular journal in mind, in which publishing such a paper is rather easy (doable) and does not have a long waiting list for review??

Looking forward to your suggestions

Thanx a lot

impact damage due to laminar construction??

Hi everyone,

 

According to a book chapter written by NL Hancox, 'Laminar construction of composites which is required if the reinforcing fibres are to be used efficiently and anisotropy reduced, can be a reason why composite laminates are vulnerable to impact damage.'

Now I have three questions;

1-What is meant here by the specified 'laminar construction to reduce anisotropy'?Does it mean to use different orientation for fibres in each ply to have an isotropic material at the laminate level?

Coupled thermo-structural analysis of CFRP using ANSYS

Hi everyone,

 does anyone know publications dealing with the coupled thermo-structural analysis (direct method) of CFRP using ANSYS?

Two postdocs at U. Pittsburgh

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.

Unit cell modeling using Abaqus submodeling

Hi,

I was going though papers related to micromechanical modeling of composites using unit cell approach. Usually in this procedure, a unit cell is isolated from the material and to ensure the compatabilty of the unit cell boundary, periodic boundary conditions are applied.

To ensure the compatabilty of the boundary and to apply loads, can we use submodeling techniques available in ABAQUS.

Thank you

Regards

mesh dependence of continuum damage mechanics approach

Hello Everyone,

I am a beginner in FEA of composites under impact in commercial explicit code Pam Crash.I want to know why the behaviour of composite plies with CDM approach show mesh dependency?Or a more general question for me is that what makes the FE simulation of a material with strain softening behavior mesh dependence(If this conclusion is right)? Does it make any difference with regard to mesh dependency if one uses implicit codes??

Thanks

Reliability and engineering mechanics

The word "failure" can mean different things to different people.  Over the past couple of years, my interactions with various groups from industry has shown me that for some people failure means catastropic fracture/buckling while for others it can mean highly localized plastic yielding.  Even for relatively simple sandwich composite structures, there is no clearly agreed upon definition of the word.

ECCOMAS Thematic Conference on the Mechanical Response of Composites - Abstract Deadline 17 December

The conference provides an efficient platform for experts on composites analysis. We are very pleased that the 2011 Public Forum of the EU Project MAAXIMUS (More Affordable Aircraft through eXtended, Integrated and Mature nUmerical Sizing, www.maaximus.eu) will be part of our ECCOMAS Thematic Conference.

Lecture Notes on Composites

In addition to the notes on stability that I've already posted, I have a set on Composites, which also originated from a lecture course that I gave in Ecole Polytechnique, around 2002. In the hope that they may be of interest at least to someone, here they are! Please do remember that they are just notes and may not be error-free.
