Postdoc or summer school knowledge

Submitted by oybozkurt on

Hi, I finished my PhD and I am looking for a summer school or a language school in English. And also I want to improve my Meshfree knowledge and programming knowledge. My education is funded by government ( or my university). How can I find a school or university? And what is the procedure for acceptance? 

question on rotation tensors

Hi,

I am doing a self-study on continuum mechanics and have the following question on rotation tensors that I would like to get answered with your help:

 

How would one come up with the rotation tensor in 3D when the axis and the angle of rotation is given. For e.g., what would be the rotation tensor in cartesian coordinates when I would like to rotate the system about n(e_1 + e_2 + e_3) by say +60 deg.

 

Thanks in advance

Pin joint modeling using Continuum Plane Stress

Submitted by Mehdi Naderi on

Dear All,

I will appreciate if you answer my question.

I modeled a 2D pin joint in ABAQUS using USDFLD to apply failure criteria.

 

I used CPS4 element for (0/90)s. As you know, the elements of both two layers completely overlap.

Abaqus gives a cotour of all layers together (bothe 0 and 90 deg.). How I can only, for example, see the contour of 90 deg. ply or only 0 deg. ply? 

In the output plots, how can i see stress or any field variable output for each layer? 

 

Regards,

Mehdi

Please recommend a good undergraduate textbook for 'mechanical vibrations'...

Thanks in advance.

what a hypocritical website this is.... almost 200 reads and not one comment. high academic qualifications of most members seems to be creating an elastic sheath of EGO!

Thanks for reading this too. :)

Hello everyone!

I have few questions about the sapphire crystal-

1. does anyone know what is the yield strain of this material?

2. is this material can be recycled? and if yes, in which method would it be?

thanks, and it will be great if you have any site that has this information
