Reducing the number of degrees of freedom

Submitted by kajalschopra on
Forums
Computational Mechanics Forum

I have been reading the book by Prof Anil K Chopra on Structural Dynamics. You might all be aware that Prof Chopra is from University of California Berkeley.

I have been reading the chapter 14, wherein the author talk of reducing the dynamic degrees of freedom using Rayleigh Ritz method.My question is, in commercial FE software , is the reduction of dynamic degrees of freedom practised?

If yes, what are the methods used? IS Rayl;eigh Ritz approiach used?

This paper uses the thermodynamic data of aqueous solutions of uncrosslinked poly(N-isopropylacrylamide) (PNIPAM) to study the phase transition of PNIPAM hydrogels.  At a low temperature, uncrosslinked PNIPAM  can be dissolved in water and form a homogenous liquid  solution.  When the temperature is increased, the solution separates into two liquid phases with different concentrations of the polymer.   Covalently crosslinked PNIPAM, however, does not dissolve in water, but can imbibe water and form a hydrogel.  When the temperature is changed

Dear Colleagues,

I would like to bring your attention to the contest on "Modeling and Simulation of Nano/Microsystems" at the University of Michigan. This is an international competition.

The objective of this contest is to provide publicity and
promotional support to new developments, recent progress, and advances
in the modeling and simulation of Micro/Nanosystems. The emphasis is on
current challenges in understanding of the multi-physics/multi-scale
phenomena that govern such systems functionality.
