We need a travelling long distance microscope for measurement of crack length

Submitted by kaslantas on

Hi

I am looking for a travelling long distance microscope for measurement of crack length. I will use this microscope on Instron fatigue test machine. I found some long distance microscopes on the web. But they are not appropriate for us. I attached a figure showing the travelling microscope that I would like to buy.

Do you have any suggestion about it? Where can I find it?

Thanks 

ANSYS Simulation

Submitted by shneerow on

Dear All,

 Is there a source of free material data property files for use in ANSYS Simulation? I am looking for a file representing the properties of Neodymium Iron Boron (38) (permanent magnet material) to apply to a simulation of a motor. 

 Thanks for any help!

iMechanica is ranked among top engineering blogs

Submitted by Zhigang Suo on

From time to time people ask if I know other websites like iMechanica but focusing on different branches of engineering.  This morning I saw a recently compiled list of Top Engineering Blogs, and was delighted that iMechanica was ranked close to the top.  I'm aware of the widespread cynicisms among iMechanicians about rankings of all kinds.  But, heck, ranking is good if you are ranked high.  As Freeman Dyson would say, being consistent is a weakness of mind. 

Research on the plasticity/damage coupling model using continuum damage mechanics

Submitted by pfliu@zju.edu.cn on

Currently, i am now attempting to establish a plasticity/damage coupling model using continuum damage mechanics for complex metal structures such as steel pressure vessel, which can be implemented using finite element analysis. The model can predict the progressive failure and damage evolution as well as the crack initiation and propogation due to large plastic deformation of metal structures. Who can give me some suggestion or idea?
