Hello everyone,

In mixed-mode CZM in Abaqus, it seems that the fracture load in not sensitive to mode II fracture energy as the cohesive elements undergo mostly opening deformation. However, when I model elastic properties for the material, it undergoes both opening and shear displacements. It means CZM elments don't model the deformation properly. Even change in relative stiffness couldn't solve the issue. Has anybody faced this problem? If CZM elements cannot represent the deformation well, what have people done in the literature to find the failure load for mixed-mode loading?

Dear all,

I have a dummy question, but it seems there is no universally accepted answer. For a general structure subject to a cyclic loading with constant ampitude, we use FEA program to run stress analysis under peak and valley load point respectively. Now, we need to post process the FEA result to come up with the stress range that will be plugged into S-N curve to come up with a "N" value.

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.

!!!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...

Dear Colleagues,

we are glad to present the Summer School on Fatigue and Damage Mechanics of Composite Materials (13 . 17 July 2015) and the Short Course on Experimental Techniques and Testing of Composite Materials (9 . 10 July 2015) organized by and to be held at The Department of Management and Engineering  - University of Padova in Vicenza - Italy.

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.
