Size Effect

Dear Mechanicians,

     I am wondering with the size eff€ect in solids with quasibrittle materials.  What is the basic behind Size effect in structural materials. Thanks for your comments.

How to copy particular results from a text file to another in Matlab

!!!Hii every body!!! Wish you all a very good day!

I am searching for opinions how to copy particular results from one text files to anothers. (You may assume I have a text files , unformatted, like a paragraph, and then starts 3 rows and 2 columns numeric values. I have to delete all the characters/strings, just want those 3rows and 2 cols; or copy those 3rows and 2 cols, anyway... I want to extract those via Matlab). I know it may be stupid question nut I am confused :p :-)

Thanks in adv...

Design and Optimization of Fans & Blowers Live Webinar | 22nd April

This webinar will highlight the application of 3D Inverse Design and TURBOdesign Suite to the design and optimization of fans and blowers for high stage performance and noise reduction.

The webinar is aimed at all fan and blowers design engineers and design managers looking to enhance their knowledge and understanding of the complex flow physics required to enhance fan and blowers stage performance while reducing noise.

Short Abstract:

How to deform an existing mesh from CT measurements?

Hi all,

I would like to know if someone has a trick to deform a mesh generated in Abaqus thanks to Computer Tomography measurements ? 

The file I received from CT is a .stl.

Do you know an open source software that can compute deviations between point clouds?

Thanks in advance for your support :-D

Post-doctoral position in Montréal on crystal plasticity in collaboration with the aerospace industry

Hi

I am looking for a 12-15 months post-doctoral fellow to work on crystal plasticity finite element simulation of impacts. This project is parts of a larger collaborative project with Pratt and Whitney, Bell Helicopter, L3 and Héroux Devtek aiming at understanding the effects of shot peening on fatigue life. The project involves 3 other post-doctoral fellows and 4 PhD students.

The starting date is flexible and could be as soon as now, depending on the candidates expertise.

The interested candidates are invited to send me their CV and publication lists.

Essential Electrical Products for Industries

When Thomas Alva Edison first invented the practical electric light bulb in the late 18th century, he never would have imagined that his inventions would someday become a necessity for living and industrial production. Since that first possibility that electricity can be used in different applications in practical life, various experiments and innovations have guaranteed the introduction of different electrical devices and products.

Share/run engineering simulation codes in the cloud

I know the mechanics community have many codes to share. If you have developed engineering software including legacy Windows codes or linux codes, you can easily publish your code in the cloud and have it run on any devices including smart phones through cdmHUB.org. The codes could be simple codes you wrote for your dissertation or comprehensive commerical package like ABAQUS or ANSYS. You don't have to change your code, no source codes are needed. All you need to do is to upload your executable through a very straight forward way which only takes a few minutes.

Will the virtual work be valid in finite deformation?

"We see from the above that the virtual work statement is precisely the weak form of equilibrium equations and is valid for non-linear as well as linear stress-strain (or stress-strain rate) relations." --- written by O.C. Zienkiewicz etc. at Page 71 of <The Finite Element Method: Its Basis and Fundamentals  Sixth edition>

 

Here is my question: Will the virtual work still be valid for the case of non-linear strain-displacement relations (finite deformation)?
