Postdoctoral position in Computational Mechanics at Vanderbilt University

Applications are invited for a postdoctoral position (open immediately) in the department of Civil and Environmental Engineering at Vanderbilt University. The candidate will conduct research in the broad area of computational solid mechanics and is expected to contribute to one or both of the following ongoing projects:

1) Modeling the mechano-electrochemistry of corrosive dissolution or dealloying of metal alloys. 

2) Wave propagation in acoustic, elastic and viscoelastic media relevant to ultrasound imaging of biological tissues.

Cracking of the concrete cover due to reinforcement corrosion

Dear all,

 Our paper titled "Cracking of the concrete cover due to reinforcement corrosion: A two-dimensional lattice model study"
 has just been published in Construction and Building Materials. It deals with numerical modelling of cracking of the concrete cover as a consequence of reinforcement corrosion, based on the Delft lattice model framework.

Corrosion modelling in COMSOL 4.2

Hello everybody,

 

I am trying to model corrosion process of steel-reinforcement embedded in concrete with COMSOL 4.2 version.

 So, please anybody has any suggestion how to do it..

 Well, if there are any other software which can model corrosion in a more simple way, please suggest that also.

 

Thanks. 

A day in the life...

New experiments on cracking and corrosion of steel in concrete performed by the M3C4 team. More details at http://microlab-m3c4.blogspot.nl/

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!

Research assistant and PhD position at PoliMi on corrosion-fatigue

Raiway axle failures have been the starting point for the studies on fatigue. However, recent accidents and papers (see [1] by Hoddinott) have shown that corrosion-fatigue plays a significant role.

At PoliMi we have recently investigated this topic finding interesting results by corrosion-fatigue tests on small-scale specimens and, recently, a validation of the model by full-scale corrosion-fatigue tests (see papers [2-3]).

Subsea Integrity

I am teaching Subsea Integrity for the MSc students majoring in Subsea Engineering at the School of Engineering, University of Aberdeen. This is a course that combines the fundamental principles (corrosion, fracture, fatigue and material selection) with the industry applications (subsea integrity management and implementation, cathodic protection, case studies on subsea reliability and engineering assurance).

Program available for 1st IC Abrasive Processes

The oral presentation program for the 1st International Conference on Abrasive Processes (ICAP-1) is now available at the conference website (www.icap.elsevier.com). Evolving from earlier meetings [the International Conference on Liquid and Solid Impact (ELSI-IX) and the International Conference on Erosive and Abrasive Wear (ICEAW-II)], ICAP-1 will be held in the historic city of Cambridge, England, 21-25 September 2008. You are invited to join your peers by registering for this popular single-stream meeting.

Environmental Effects on Crack Characteristics for OSG Interconnect Materials

Jeannette M. Jacques, Ting Y. Tsui, Andrew J. McKerrow, and Robert Kraft

To improve capacitance delay performance of the advanced back-end-of-line (BEOL) structures, low dielectric constant organosilicate glass (OSG) has emerged as the predominant choice for intermetal insulator. The material has a characteristic tensile residual stress and low fracture toughness. A potential failure mechanism for this class of low-k dielectric films is catastrophic fracture due to channel cracking. During fabrication, channel cracks can also form in a time-dependent manner due to exposure to a particular environmental condition, commonly known as stress-corrosion cracking. Within this work, the environmental impacts of pressure, ambient, temperature, solution pH, and solvents upon the channel cracking of OSG thin films are characterized. Storage under high vacuum conditions and exposure to flowing dry nitrogen gas can significantly lower crack propagation rates. Cracking rates experience little fluctuation as a function of solution pH; however, exposure to aqueous solutions can increase the growth rate by three orders of magnitude.
