This paper presents the theory for the Lagrange co-rotational (CR) formulation of finite elements in the geometrically nonlinear analysis of 3D structures. In this paper, strains are assumed to be small while the magnitude of rotations from the reference configuration is not restricted. A new best fit rotator and consistent spin filter is derived.

Hi,
I am looking for a good citation (or perhaps a detailed explaination) on the difference between material co-ordinate and eulerian co-ordinate system.Please treat me a beginner in the field of continuum mechanics.Thanks for your help in advance.

Hi All  Currently I am running FE modelling using linear elastic fracture mechanics approach to estimate crack growth propagation in a web plate of box girder in an existing bridge deck. The FE model includes 3D solid element. The crack growth direction is expected to follow in a plan perpendicular to the maximum principal stress.  As I know there are many methods can be used to estimate the direction of crack during propagation. My question is about the maximum tangential stress criterion method.

I am co-organizing a mini-symposium on Cohesive Zone Models –
Fundamentals and Multiscale Applications (MS-139) in
the World Congress on Computational Mechanics (WCCM 2012) with Dr.
Glaucio H. Paulino at the University of Illinois at
Urbana-Champaign. We welcome papers that present theory and
applications of cohesive zone models at any length and time scales,
from atomistic and molecular to microstructural and phenomenological
models. Please, see the attached PDF for more detail of the
mini-symposium.

Abstract

 Dear friends

 The obtained results from my model show that the ultimate load is higher
than the expected one. after checking the results, I found out that the
tensile stress of concrete is much higher than input value for the
tensile yield stress. "concrete damaged plasticity model"  is applied.
your help is highly appreciated.

Czech Society of Mechanics Institutes Z.P. Bazant Prize for Engineering Mechanics

The Czech Society of Mechanics, Prague, has instituted the Z.P. Bazant Prize for Engineering Mechanics,
in honor of Prof. Zdenek P. Bazant, the McCormick Professor and Walter
P. Murphy Professor Of Civil Engineering And Materials Science. The selection
committee is composed of members from the Czech Technical University
and the Czech Academy of Sciences. The Prize is to be given annually.

I have divided the old notes on temperature into three parts:

• Principle of the conservation of energy
• Empirical observations of temperature (this part)
• Energy and fundamental postulate 

Our feeling of hotness comes from everyday experiences. These experiences indicate that many levels of hotness exist, and that all levels of hotness can be mapped to a real variable.

Enthusiastic and highly motivated postdoctoral scientists are sought to work with Dr. Kun Zhou at the School of Mechanical and Aerospace Engineering, Nanyang Technological University, Singapore on the following areas:  

A full time Postdoctoral position is available immediately in the Sensory Motor Performance Program at The Rehabilitation Institute of Chicago. 

Under the general supervision of the assigned Senior Research Scientist, the Post Doc Fellow will be responsible for the development of a three-dimensional multi-scale finite element model of the human knee, and will compute the stress/strain fields in the joint soft tissues before and after common orthopaedic surgeries using three-dimensional hyper-elastic formulation.

We welcome applications for a fully funded PhD position in the field of experimental mechanics and materials science. Further details in the attachment.

Abstract:A hydrostatically coupled dielectric elastomer (HCDE) actuator consists of two membranes of a dielectric elastomer, clamped with rigid circular rings.  Confined between the membranes is a fixed volume of a fluid, which couples the movements of the two membranes when a voltage or a force is applied.  This paper presents a computational model of the actuator, assuming that the membranes are neo-Hookean, capable of large and axisymmetric deformation.  The voltage-induced deformation is described by

Using a new experimental setup have now proved that one could actually draw a thermal conductivity-strain relationship in the same way as stress-strain relation!

What remains to be seen is that whether this relationship is tensorial or not! Details are in the paper..
