EC FUNDED WORKSHOP ON PHYSICS BASED MODELING OF MATERIALS, Ankara, October 22-23

The objective of the workshop, co-organized by Joint Research Centre of the European Commission and Middle East Technical University, is to discuss the present status of physics based constitutive modelling of metallic materials and associated experimental methods.

The Workshop is funded by the European Commission's Integration and Enlargment Programme.  There is no cost for attending the Workshop. A limited number of scholarships is available for participants from the target countries (see attached flyer).

Corrosion rates of reinforcing steel in cracked concrete

Hi all,

 

In the course of our project, we are monitoring the corrosion behavior of steel reinforcement in cracked concrete, while exposed to simulated sea water. Recent results are posted on our blog,  http://microlab-m3c4.blogspot.nl/ ! Be sure to check them out! For more information, you can contact us, or follow us on twitter @MicrolabM3C4.

 

Cheers!

Rupture of a highly stretchable acrylic dielectric elastomer (VHB)

Dielectric elastomer transducers are often subject to large tensile stretches and are susceptible to rupture. Here we carry out an experimental study of the rupture behavior of membranes of an acrylic dielectric elastomer (VHB 4905). Pure-shear test specimens are used to measure force-displacement curves, using samples with and without pre-cracks. We find that introducing a pre-crack into a membrane drastically reduces the stretch at rupture. Furthermore, we measure the stretch at rupture and fracture energy using samples of different heights at various stretch-rates. The stretch at rupture is found to decrease with sample height, and the fracture energy is found to increase with stretch-rate.

Call for abstracts: “Computational Modeling of Damage and Fracture in Solids”, SES 2012, Atlanta GA

As part of the 49th Annual Technical meeting of the Society of Engineering Science   (SES 2012) to be held in Georgia Tech, Atlanta, GA, on 10-12 of October , 2012, it is our pleasure to invite you to submit an abstract to the Symposium “Computational Modeling of Damage and Fracture in Solids”.

POST DOCTORAL POSITIONS

One (1) to Two(2) years post-doctoral positions are open in Ecuador (South America). The following are areas of interest:

Postdoctoral positions in statistical modeling of fracture and plasticity

We anticipate the opening of four postdoctoral positions in 2012 to work on statistical aspects of fracture and plasticity,  and in particular on size effects in the fracture of  disordered media and in microplasticity.  The positions will be funded by the ERC Advanced Grant 2011, SIZEFFECTS.

Cohesive crack - how to verify model? Cant figure out how to output stress intensity factor...

Hello,

I am simulating crack propagation with cohesive elements. In order to verify that my model is working correctly I wanted to compare it to some real world data or benchmark examples. One such example is in the Abaqus Benchmarks manual - a flat plate with a crack in the center.

Damage tolerance of railway axles

Failure of railway axles has been the problem which gave origin to the studies about 'fatigue'. The modern approach to the structural integrity of these safety components is to complement the traditional designwith a 'damage toleranc' analysis.
