Open hole shear strength test method

Submitted by syn1003 on

Hello

I am wondering test method about open hole specimen to acquire shear strength.

The specimen is made of composite and we tried to make fixture from ASTM D5379.

However the failure mode is not acceptable and I am thinking about new test method for

open hole specimen.

Let me know any idea to approach other test method to acquire open hole shear strength value.

Thanks

Inverse eigenstrain analysis based on residual strains in the case of small strain geometric nonlinearity

Submitted by Sébastien Turcaud on

Hi,

I was wondering if someone knows literature related to "Inverse eigenstrain analysis based on residual strains in the case of small strain geometric nonlinearity"? (elongated bodies)

In the case of lineralized elasticity I guess one could postulate an eigenstrain distribution as the sum of a finite set of basic eigenstrain distribution and minimize the difference between the predicted and the actual residual strain distribution (retrieved from a synchroton mapping for example).

As done in the paper:

Python scripting

Submitted by villa7 on

Hello

I am reading an abaqus odb which is solved for 2 time steps 'step1' and 'step2' and i want to read  the output at every last frame of these steps.  further, I have written python script to find change in dispacement. I have written this code which works fine to capture delta displacement

Mechanics dictates embryonic stem cell pluripotency

Submitted by Ning Wang on

We demonstrate that a soft substrate of a stiffness that matches the embryonic stem cell stiffness can promote homogenous self-renewal and pluripotency of these cells, even in the absence of the growth factor-Leukemia Inhibitory Factor (LIF). These findings open the field of stem cell biology for long term culture of embryonic stem cells without generating a heterogeneous population of cells with varying degrees of differentiation and highlight the importance of mechanics in dictating embryonic stem cell pluripotency.

Teaching Engineering Thermodynamics to Undergraduate Students

Submitted by Zhigang Suo on

I have just volunteered to teach engineering thermodynamics to undergraduates in the Fall semester of 2011.  The students will be from all fields of engineering, primarily mechanical engineering, environmental engineering, and bioengineering.  I have never taught this course before, and would love to hear from you about your experience, either as a student or as a teacher. 

Here is what I have found from the website about the course.
