A short-beam shear fracture approach to measure the mode II fracture toughness of materials with preferred interfaces
Increasing complexity of numerical simulations has made it important to obtain reliable experimental data for a variety of mechanical properties. Fracture properties are complex to measure but accurate data is often desirable for several challenging problems. We have developed a novel short-beam shear fracture approach in order to measure the mode-II fracture toughness properties of materials with 'preferred' interfaces.
Free Webinar: Retrofitting of Turbomachinery - from Scanned Data to a New Efficient Flow Path
SoftInWay has scheduled the next free webinar on turbomachinery retrofitting techniques used to increase efficiency using AxSTREAM. The webinar will be held on April 28, 2011, at 10 a.m. and 4 p.m. EST.
The SoftInWay team will present the full redesign process to the attendees: starting from analyzing scanned data and determining profile characteristics, followed with 1D/2D analysis of existing flow path, evaluation and selection of sections which require redesign and finally the design of new and efficient airfoils.
Help Regarding composite material Analysis in Ansys
hello to all,
I m new to composite material analysis, I am doing a project for wind turbine analysis in ansys. The wind turbine contains total 96 layers of two different material which is stacked alternatlly. i dont know about the modelling and analysis procedure of composites. i don't understand how to connect the surfaces.
thanking you..............

ASM Educational Symposium: Innovations in Mechanical Testing: From Molecules to Large Engineering Structures
Dear iMechanica Readers,
Greetings from Oak Ridge.
I would like to invite you, your colleagues and students to attend the annual Educational Symposium organized by the Oak Ridge Chapter of ASM International. The theme for this year’s symposium is:
“Innovations in Mechanical Testing: From Molecules to Large Engineering Structures”
We have an outstanding list of speakers, which includes:

FEM simulations of indentation test
Hello Everybody,
Does anybody have experience with simulations of indentation in axysymmetrical case, it seems that adaptive meshing doesn't work in ABAQUS Standard.
Best regards

Ansys File Import
I am working on a FEM project in which i should import a complicated 3D model to Ansys.
I created The IGES format of the model which the size was 52Mb for the IGES file.The model contains very curvy surfaces and it is complicated.it is created By 3D doctor....
when i import it to ANSYS it doesnt create any volume and i can see only small areas.
now how can i make the model more handy for ansys....also i need to have a volume in order to meshing....
could u please help me to get out through this?
Thanks
Computing Thermal Stresses for Composite using ABAQUS/CAE
Hi,
I am new in ABAQUS. I am trying to find the thermal stresses created by change in temparature of 50'C for lainate consisting of [90/+45/-45/0]s configuration. Eventually what I intend to do is find the stresses under a simple uniaxial load which also consider the change of temperature while calculating the stresses in each ply. I have the material data for the coefficinet of thermal expansion both for longitudinal and trnasverse directions (alpha_11 and alpha_22).
Is there any suggetion of approches I may take.
Many thanks in advane !!!!
