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).

Pressurized Cylinder FEM constraint

Submitted by fernando.romagnoli on

Dears,

 

I have a cylinder subjected to an internal pressure of 10 MPa, the cylinder diameter is 1400 mm. I am trying to model it in my FEMAP. I am comparing the average stress (TOP and BOT Y) with the stress that come from the formula

hoop_stress=pressure.Radius/thickness

The stress I obtained is similar with the one that is from the formula, but the deformed is not equal, it is crazy !

Fully funded PhD scholarship in Vienna, Austria. Research topic is the behaviour of granular materials.

Submitted by Markus Wawra on

Fully funded PhD scholarschip for 3 years is available at the Institute of Geotechnical Engineering, Universität für Bodenkultur, Vienna, Austria. The research topic is the behaviour of granular materials. We expect a candidate with solid background in continuum mechanics and constitutive modelling. Some knowledge of DEM (discrete element method) will be a benefit. This project is financed by the European Commission within its Marie Curie Programme. There are some ten international partners in this project. During the project you will visit our partners in UK, Germany, Holland and France.

Fully funded PhD scholarship in Vienna, Austria. Research topic is the stability of earth slopes of unsaturated soil.

Submitted by Markus Wawra on

A fully funded PhD scholarschip for 3 years is available at the Institute of Geotechnical Engineering, Universität für Bodenkultur, Vienna, Austria. The research topic is the stability of earth slopes of unsaturated soil. We expect a candidate with solid background in continuum mechanics. Some knowledge in constitutive modelling of soil and numerical analysis (finite element and finite difference) will be a benefit. This is a joint project with Stanford University, USA. The candidate will visit and stay in Stanford for some time. Your thesis will be co-supervised by Prof.

Saint-Venant’s Principle and Its Proof : History and Review

Submitted by Jian-zhong Zhao on

In this article the history of development of Saint-Venant’s Principle is reviewed, referring to the most important events concerning the principle as the historical clue, and the important works and results are evaluated; the view-points that Toupin Theorem can not be considered as a mathematical expression of Saint-Venant’s Principle and that the general Saint-Venant’s Principle does not stand, but modified Saint-Venant’s principles can be proved true are published and explained; the mathematical approaches for eslablishing modified Saint-Venant’s principles are summarized; the significan

Business venture - seeking support from like minded people from India:

Submitted by Gopinath Venkatesan on

I am coming back to India in the September 2009, and with only a month to go, I am thinking about joining likeminded individuals to open up a small consultancy group and see where it goes. We can also teach CAD/FEM side by side (during day time, and work on projects in the evenings/night - flexible times). Presently I am thinking of buying 1 Ansys Professional (which is very expensive, atleast to me) license. If you have other suggestions, please write to me in detail. I look forward to suggestions from the experienced persons.
