For hardware based method, you can use an independent timer to trigger off the counter to measure the number of speed pulses in a suitable frequency, such as 1MHz. In that case, the time interval you obtained is so small that it apporaches to zero.
Instantaneous Angular Speed (IAS) is investigated for last 10 years in Condition Monitoring. The content of IAS is coming from angular speed. If the time taken is reduced apporaching to zero, we can measure the angle travelled to extract IAS, or if the angle travelled is reduced to zero, we can measure the time elapsed to extract IAS.
I've been to two conferences this year and I've again seen the same annoying features in many talks that have been warned against by numerous people over the years.
Here are some tips that might come in handy :
Hi Dear fellow Mechanicians
I am Ali Nojoumi a M.Sc. Civil engineer and I'm modleing shape memory alloys using in concrete shear walls to reduce the effects of earthquakes...
making my Model by ABAQUS, I should use UserSubroutine to define such SuperElastic behavior How can I manage that and have anyone ever done this?
I would be glad to have your suggestions or any contribution.
thanks alot; AliNojumi@GMAIL

The above was written for the interested layperson who wants to learn more about science. It provides some context for our manuscript that has recently appeared in Nature.
Dear friends,
Can anybody give me information/Website/papers/... on below mentioned topic ??
on Johnson Cook plasticity model with analytical forms of the hardening law and rate dependence. I am trying to use this in my high-strain-rate transient dynamic simulations (metals). I am using ABAQUS as analysis tool.
Thanks a ton in advance !

In a paper published July 26 in the journal Nature, researchers led by Rod Ruoff, John Evans Professor of Nanoengineering in the Robert R. McCormick School of Engineering and Applied Science, report on the development of "graphene oxide paper."
