recovery strain

Min Huang — Sat, 12 Nov 2011 17:40:26 -0500

Thank you. The recovery strain is to describe the plastic strain decrement due to dislocation recovery. The details of this term is discussed in Ref. 4 (Khadhraoui, et al. Materials Science and Engineering 1997, 13: 360-367).

Nice work -- would you

Nice work -- would you explain a little more on the recovery strain term? I guess there are experimental measurements in linking this term with the applied temperature etc.

The first consumer product of dielectric elastomers is available

The first consumer product of dielectric elastomers, Pulse™, is now available.

A video for Pulse, a haptic device using dielectric elastomer

Here is a video for Pulse. It is too brief to show how it works, though.

How to assign Hardness in abaqus

Sir

May i get some help plz

We are IIT Bombay students

Doing a project

How to assign Hardness value in abaqus

In experiments as hardness increasing, load also increasing, it observed

Thanking you

Decision making challenged by uncertainties and lack of data

Henry Tan — Mon, 09 May 2011 09:11:00 -0400

I will give a presentation at the Oil & gas Pipeline Integrity Management Summit , 12th and 13th October 2011, Aberdeen, UK.

Decision making in maintenance: Effectively managing and overcoming uncertainties caused by a lack of available data.
·         Assessing the need for condition-based maintenance and the challenges associated with this approach
·         Conducting a comprehensive risk-based assessment of assets and the specific methodologies involved
·         Overcoming the uncertainties which often arise during maintenance procedures
·         Revealing the specifics of Bayesian network modelling

Adopting the Right Risk-Based Mitigation Strategy

Henry Tan — Sun, 20 Feb 2011 06:56:00 -0500

I will deliver an opening address “Structural Integrity Management: Adopting the Right Risk-Based Mitigation Strategy” at the 5th Annual Pipeline Integrity Management & Maintenance Forum, 23rd- 25th March 2011, London. My topics will include:
• Securing immediate repair prioritisation
• Extending operations safely beyond original design life
• Implementing a systematic managed approach to defects, repairs and replacement
• Developing effective pipeline response schemes: corrosion control.

Conference focus:

The demand for new pipelines and the constant need to rehabilitate existing ones are increasingly growing around the globe. A failure in the pipeline system could have serious implications for the whole production cycle, causing environmental damages and monetary loss.

Pipeline integrity has to be at the top of operators’ agendas to ensure reliable and safe operations and maximise returns. Operators need to sustain their current infrastructure as the success of pipeline projects depends on their operational availability and life expectancy.

Literature regarding the appearence of cracks

Panos Efthymiadis — Sun, 23 Jan 2011 07:00:44 -0500

Hi Daniel,

fatigue in general is quite a big subject. Are you looking for literature on fatigue crack initiation or more into the crack propagation period? And you also have differences between High Cycle Fatigue and Low Cycle Fatigue. I would suggest that you go through the papers of K.J Miller. Especially the one called: Metal Fatigue: Past, present and future.

But you need to be more specific, what size of crack you want to investigate and what's the loading you are having. The orientation of tha crack, the crack path, as well as the crack speed can tell you information about your loading system.

Regards,

Panos

Dying pipelines?

Henry Tan — Fri, 08 Oct 2010 11:34:00 -0400

The majority of the world's offshore infrastructure begins to reach the end of its original design life.

More than a quarter of the North Sea oil & gas production pipeline network was first commissioned in 1960’s and 70’s. Other 23% was build during the 80’s. Those pipelines were originally designed to operate around a period 20 years.

How to deal with old pipelines become a urgent and challenging issue.

Extension of the industry roundtable discussion

Henry Tan — Fri, 08 Oct 2010 11:28:00 -0400

The discussions topics on the roundtable today were intriguing. I created this forum for several purposes:

(1)    To keep the discussion rolling among the delegates and others world widely;
(2)    To benefit my research;
(3)    To bring the conference themes to my students who are taking the Subsea Integrity course I am lecturing.
