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).
Early bird registraion is open for the 2010 SCC which will be held May 25 - May 27, 2010 at the Rhode Island Convention Center in Providence, RI, just a short distance from SIMULIA's world headquarters.
There will be more than 80 customer presentations over the course of the 2 1/2 day conference. Advanced Seminars are offered on Monday May 24.
All users of SIMULIA products including Abaqus FEA, Isight, Fiper, and SIMULIA SLM invited to register for the conference.
A fully funded PhD position is available in the area of multi-scale modeling of geomaterials within the research project Failure of cohesive geomaterials: bridging the scales - GEOBRIDGE at Laboratoire Sols, Solides, Structures – Risques (3S-R), Université Joseph Fourier, Grenoble, France.
there are two analytical concepts that are very important in fatigue failure.the first one is crack closure and the others is residual stress .the first one is in behind of crack and the other emphasis in the front of crack tip. the question is if we use some devices such as AFM/SEM is it possible we model the energy filed during fatigue process? if this idea can be investigated the second question can be asked: is there any similarity to model for different loading conditions?
I appreciate if you also put your comment in my idea?
Among various low-dielectric constant low-k materials under development, organosilicate glassesOSGs containing nanometer-size pores are leading candidates for use as intrametal dielectrics infuture microelectronics technologies. In this paper, we investigate the direct impact of waterdiffusion on the fracture behavior of film stacks that contain porous OSG coatings.
For a flexible electronic device integrating inorganic materials on a polymer substrate, the polymer can deform substantially, but the inorganic materials usually fracture at small strains.This paper describes an approach to make such a device highly stretchable.A polyimide substrate is first coated with a thin layer of an elastomer, on top of which SiNx islands are fabricated.When the substrate is stretched to a large strain, the SiNx islands remain intact.Calculations confirm that the elastomer reduces the
In a lithium-ion battery, both electrodes are atomic frameworks that host mobile lithium ions. When the battery is being charged or discharged, lithium ions diffuse from one electrode to the other. Such an insertion reaction deforms the electrodes, and may cause the electrodes to crack. This paper uses fracture mechanics to determine the critical conditions to avert cracking. The method is applied to cracks induced by the mismatch between phases in crystalline particles of LiFePO4
I guess it is about time some one from the Cornell Fracture Group got on this site to try help answer questions related to the CFG software or other fracture mechanics related questions. We do try to answer questions sent to us via email, but sometimes a forum like this would be best and we do appreciate other users input, feedback, and answers.
This is topic 12-21 Advanced Computational Methods for Fracture in the upcoming ASME Congress 2009 (November 13-19, Lake Buena Vista, FL., USA.) Deadline for abstract submissio: March 2, 2009.
The aim of the topic is to recognize the recent development in the computational tools for fracture characterization. The topic is open to all contributions on numerical techniques, simulations of fracture problems at all length scales, failure mechanism modeling, fracture prediction, and computational algorithms to achieve these goals.
I am new to Abaqus: I am trying to model formation and propagation of fractures in glacial ice (note: ice deformation mainly by plastic flow). I was wondering if anyone has modeled ice as a material exhibiting a nonlinear behavior, or possibly have a user subroutine for ice that I could use. Thanks in advance for any help.
Can anyone please suggest material for Cohesive Failure Model. I need to know the basic concepts that deals with cohesive failure model. I would also like to know how deltanc, deltatc etc are formulated in this model. Please sugggest.
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.
