Flexural-Torsional behavior of thin-walled composite beams

Submitted by composite20 on

I'me a student at the Departement of Civile Engineering of university of the algeria.

currently, i'm working on completing my thesis. My research area in general is in mechanics of composite materials. My problem is that of formulating the FEM solution to the Flexural-Torsional of laminate composite beam having orthotropic layers.

To plot a variable

Submitted by nitinchandola on

Hi everybody,
 
I have a question. I am using a UMAT and calculating a variable (tau=resolved shear stress) within the UMAT using other variables calculated in the UMAT for each time step. Now I want to plot this variable. How can I do this? This variable is not  only a function of pre-defined variables but also a function of variables calculated in the UMAT. 
 
I tried going through the USDFLD, UFIELD and UVARM subroutines but could not figure this out
 

Spatial Control in the Heterogeneous Nucleation of Water

Submitted by Kripa Varanasi on

The attached paper was recently published
in Applied Physics Letters. We show for the first time that Nucleation and
Condensation of Water can be spatially controlled. Such control of nucleation
phenomena and the fundamental findings discussed in the paper have implications
for the Energy and Water industry. The paper can be found at http://link.aip.org/link/?APL/95/094101/1

Lightweight structures

Submitted by R. Gabbrielli on

For those of you interested in the geometry of light frameworks and models for extremely porous materials, here are a couple of links. The first one contains two 3D objects. You need Java to view them.

Can somebody suggest a general-purpose object oriented design of the finite element?

Submitted by Wenbin Yu on

I am looking into object oriented programing of the finite element method. I don't know whether somebody can provide a general-purpose oop design of a general finite element program, say a linear static analysis of a 3D solid. Or somebody who are experienced in this field point out some good references for this purpose. It will be better if the oop design is language free, i.e. not directly related with implementation in a specific language such as c++. Thanks in advance.
