I want to what exactly entropy means???I know the definition and formula but still not getting the physical significance.When we say temperature we can understand and feel it.But,in case of entropy each time I read about it I don't get it.Can anybody explore it's significance in easy way so that i can understand what exactly entropy means?
Does anyone know how to calculate the total energy or power of permanent magnet?
Thanks a lot
Dear imechanica Members,
Dear all,
I will model a bird to impact a shell at high velocity by ABAQUS. I decide to model the "bird" by ALE mesh and referred by EOS equation.
However, most simulation works are done by LS-Dyna. Do anyone know how to determine the parameters in ABAQUS for the "bird" in EOS equation?
All suggestions are welcome.
Thanks.
Jason,
Best regards
Hi!
I am investigating the effect of triaxial stress state on the superelastic behavior in NiTi. In this regard I have conducted some simple tensile tests on notched specimen until fracture. The next step is to investigate the fracture surfaces in SEM to determine point of initiation and the structures. However, as my knowledge in fractography is limited at best, I am not really sure what to look for to determine eg. fracture initiation.
hello all,
i have a problem with ansys, how can i simulate the crack propagation using ansys.
please help me
In May 2008, I posted 3 lectures on Soft Active Materials given at UCSB. I have since given similar lectures on other occasions, but never all three at the same place. The field has been active. The lectures have been updated with new items. I’m now posting the “2nd edition” of these lectures.
The slides are posted as delivered. No effort is made to eliminate repeating slides.
Hello All..
i am finding the MPC omega method for the devlopment of Isochronous curve..in which i am searching in the ASME catalogue but it will want 599$ so it will not affodable me...so anybody who will guide me..
