Need to know information about Hermite cubics & shape function

Submitted by gurumecc on

I am doing my research in nonlinear vibration of beams. In that research, I have to derive the shape function for different end conditions of the beam. Regarding this,I need some ideas. Are there books I can reference?

Regarding my research work, I need to know about hermite cubics in Fem. Can any one suggest a book regarding this?

Can anyone help me to get the following book?

Hi ,

I am doing phd in nonlinear vibration. Regarding my thesis, I want to refer the following book

"Analytical and numerical methods for vibration analysis" by "Jong-Shyong"

Since the cost of this book is very costly, I am not able to afford this book. I am ready to buy the used copy of this book also.

Can anyone have used copy of this book?

If anyone have, plz provide the photocopy of that book.

If anyone knows, free download copy of the book, plz let me know

Coordinate system in Abaqus data file (*.dat)

Dear all,

I have a question which seems quite simple but has troubled me for quite some time: 

I have a composite tube modeled using layered solid elements C3D8, and I want to output radial, circumferential, and axial stress components averaged at preselected nodes (defined as a node set) in Abaqus data file (*.dat). Nevertheless, I would like to have those stress components expressed in a cylindrical coordinate system, rather than in local material coordinate system. I would appreciate it a lot if anyone knows whether it is possible to do so. Thanks.

The new blog post discusses yet another application of the Linear Assignment Problem; in this case the use of the Hungarian algorithm for finding an optimal list of close data points to a set of point generated using Latin Hypercube sampling.  See http://www.parresianz.com//sampling/hungarian_algorithm/

RHEOLOGICAL MODELS

The attached notes are written for a course on plasticity.  When I update the notes, I will post a link on my twitter account:  https://twitter.com/zhigangsuo.  

Rheology is the science of deformation.  This science poses a question for every material:  Given a history of stress, how do we predict the history of strain, or the other way around?
