In addition to the notes on stability that I've already posted, I have a set on Composites, which also originated from a lecture course that I gave in Ecole Polytechnique, around 2002. In the hope that they may be of interest at least to someone, here they are! Please do remember that they are just notes and may not be error-free.
hi
i have a problem in finding the quality factor of cantilever beam (one end is fixed and other end is free ) vibrating in air /other medium? how the qualtiy factor expression for beam is calculated? whether all these expressions applicable to micro and nano cantilevers.
please explain me.
i am new to this area. i read books on vibrations of beam. i didnt get anything
please mention steps for finding quality factor of cantilever beam in air medium(damped system)

I have an idea: In abaqus, I want to simulate crack propagation by XFEM, and meanwhile I also want to define the stress update algorithm by writing a UMAT.
Anybody wants to share related experiences?
hi my friends,
i am using abaqus standard Mohr-Coloumb plasticity to model uniaxial compression test, so i have sample and (upper and lower platen) to represent the compression machine , i apply the load through the movement of the upper platen, the stress strain diagram of my material is strain softening.
The deadline for submitting abstracts has now been extended to 15 November. To submit, go to http://www.tc4pca.elsevier.com/abstractsubmission.asp
