A question on UMAT implementation of non-local theory

Submitted by Liu Jinxing on

 

Hi, friends,

Now, I am implementing the non-local continuum theory in ABAQUS through UMAT programming.

Unfortunately, I have been obstacled by the following question:

On one hand, in non-local continuum theory, the non-local strain of every particular integration point is determined by the global strain field all over the specimen.

Hi!



I am wondering if anyone here knows of a generic heat engine simulator. I.e. something that can simulate the behavior of reciprocating engines, Stirling engines, and so forth.



The outputs I'm interested in include things like power and efficiency. The input variables that I would play around with include engine dimensions and material properties.



Tensile coupon test - simulation of tensile coupons (after necking)

Submitted by ron.dana on

I have carried out several coupon tests (rectangular coupons similar to
those of ASTM E8). Some of these tests have kind of weird behavior. The
problem arises when I simulate results with ABAQUS. It goes pretty well
until a few steps after necking. Test and ABAQUS results match exactly
until several steps before fracture. After this point, there is a
discrepancy between results and my attempts in capturing the observed
behavior was unsuccessful. (around 10% or more plastic strain).

UK Newton Post-Doc Fellowship in Computational Mechanics

Submitted by Stephane Bordas on

 

Dear All,



A new multi-million pound initiative to fund research collaborations and improve links between UK and overseas researchers has been launched.



The Newton International Fellowships aim to attract the most promising, early stage, post-doctoral researchers working overseas, who do not hold UK citizenship, in the fields of humanities, engineering, natural

and social sciences.



NAFEMS NA 2008 Regional Summit: NAFEMS 2020 Vision of Engineering Analysis and Simulation (Hampton, VA - Oct. 29-31, 2008)

Submitted by nafemsNA on

Hi everyone,

I just wanted to let everyone know about the upcoming NAFEMS North American 2008 Regional Summit: NAFEMS 2020 Vision of Engineering Analysis and Simulation. This is an excellent opportunity for academic researchers, industrial practitioners and software developers to meet for mutual benefit.

For those of who you not familiar with NAFEMS, it is a non-profit, vendor neutral, engineering analyis community.
