Engineering Strain vs Logarithmic strain I would like to have your (experts) interpretation on Engineering strain and Logarithmic strain. Based on what I’ve studied, I would request your comments on what I state below in regard to Engineering strain and logarithmic strain:
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.

I’m trying to program geometric non linear analysis (finite element)-for a shallow truss element.I am using the book by Crisfield for the purpose. Basically, I am using the incremental approach for analysis.And I am struck with a problem.The problem is that my Structural stiffness matrix (after application of Boundary conditions) is singular i.e. it’s determinant value is “0”.
I am working on fracture mechanics , calculating K and J in ABAQUS
Can you please tell me how to model singularity at crack tip in Hypermesh/ABAQUS -CAE.
Do we have any tutorial available on internet ?

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.
We are currently seeking candidates for a Post-doctoral Fellow position in Theoretical and Applied Mechanics at Northwestern University. The successful candidate is expected to possess a Ph.D. in engineering or science and must have experience in the area of computational mechanics, broadly involving computational inelasticity, finite elements and continuum mechanics. Knowledge of discrete mechanics is desirable but not essential.
I am pleased to inform you that I will be defending my Ph.D. thesis, formally in mechanical engineering, at COEP, University of Pune, India, on the next Sunday (i.e. 20th September, 2009).
The title of my thesis is: "A New Approach to Computer Modeling and Analysis of Certain Fundamental Field Problems from Engineering Sciences."
Northwestern University, the Department of Civil and Environmental Engineering (CEE)and Department of Mechanical Engineering (ME) jointly seek an outstanding individual in the area of mechanics for a tenure-track position at the level of assistant professor. The successful candidate will be expected to develop an independent, internationally-recognized research program, teach graduate- and undergraduate-level courses, and supervise graduate research. Both CEE and ME
A post-doctoral position is available at Kongju National University,South Korea to work in the field of nanomechanics(atomistic modeling) or Bio/nano mechatronics.Interested candidate should send their detailed CV to Prof.Sung-Gaun Kim via email to the following email address-(kimsg [at] kongju.ac.kr).The initial contract is for one year and is extendable to multiple years subject to his/her performance and availability of funding.
Hi all,
I have a fundamental question on Tensors. The length of a vector (firts order tensor) is independent of the reference co-ordinate system. In case of second order tensor (stress/strain), the invariants (I1, I2, I3) are independent of the co-ordinate system.
If I consider 4th order tensor (of course 3rd order also), say Cijkl, what parameters are constant? (Like length in vector and invariants in second order tensors).
Thanks in advance,
- Ramdas
