ABAQUS: Thermal stresses in a rectangular composite plate

ABAQUS
composite

Trying to model a crossply square plate with a sinusoidal temperature loading (uniform along the thickness). I am trying to match the results by Kant et al 2008 and Rohwer et al 2001. I am modeling the compoosite as a 3-D solid elements (making a part and dividing into 4 layers). I always obtain transverse shear stress on the 90 degree layer at 0,b/2,z to be zero.  My results match with that of the paper when I have a single layer of orthotropic material but they dont match when I have 4 layers of equal thickness and an aspect ratio of 5 (length/thickness).

CISM; Short course; Udine;

A short course on the “Mechanics of Liquid and Solid Foams” will be offered at CISM, the International Centre for Mechanical Sciences in Udine, Italy, 13-17 July 2015 (see brochure attached).

The course will focus on relationships between the cellular microstructure and nonlinear mechanical behavior of liquid and solid foams, and foam-like biological and synthetic materials. Theoretical models, experimental methods, and numerical simulations will be presented. The course is aimed at PhD students, postdocs, and researchers in academia and industry.

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.

Sampling data from large numerical simulations - part 2

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/
