DISCUSSION THEMES 

• Assessing the potential of ageing infrastructure to provide the same level of service as newly constructed facilities
• Identifying the key threats to the integrity of a pipeline in later life
• New solutions for old pipelines: revealing how new technologies can
  help ensure reliability of older infrastructure and assessing the
  future outlook for mature pipes
• Taking the necessary steps to make sure that older pipelines are operated within regulatory requirements
• Tackling the inspection difficulties associated with ageing pipes

Materials such as sedimentary rocks, pharmaceutical tablets, plastic bonded explosives, biscuits, concretes, nacre, solid propellants, seashells and asphalts can be treated as particulate composites that consist of particles of high volume fraction, matrixes of thin layer and interfaces of high specific surface area. Mechanical behaviour of highly packed particulate composites is the theme of this issue of Journal Club forum.

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).

Teaching time schedule

Lecture note for the course (28 Sept - 2 Oct, 2009) at the International Centre for Mechanical Sciences (CISM), Udine, Italy.

As the title suggests, there are two focuses of this discussion theme: impact and cellular materials.

Impact protection can be very practical problems in safety, fires and explosions, oil and gas industry, subsea structures, car manufacturing, nuclear industry, rocket space engineering, etc.

Cellular materials are interesting as materials with visualable small structures. Shock wave propagation and interaction; gas, fluid and cell wall interactions; together with catastrophic collapse can be fancy problems to study theoretically and experimentally. In this area, continuum mechanics seems still have many challenging problems unsolved, and is useful.

Dear Moderators:
Is there anyway not to show the posts from my class (including mine) on “recent comments”?

Too many student posts (around 170 students) and my discussions with them will crowd the space of the "recent comments" section, which should be reserved for more advanced discussions that come up.

Any other suggestions on the classroom behaviours that may not be appropriate for iMechanica?

There are good reasons that I do not want to move my class website to WebCT or other places.

Thanks a lot.
Henry.

Please introduce yourself in this blog. This is a class to learn
engineering mechanics, but also a class to make friends with in-class
and international students, and worldwidely recognized experts.

On the assessment method. Thanks for many feedbacks. I will review them with you in the class.

When emailing the lecture-note to imechanica@gmail.com with the subject title as Lecture 1, please also put your information in the text message: Name, University ID, and Aerospace/Mechanical Engineering. Thanks.

1. A force is a relationship
2. A force is a vector

Newton's laws of motion

3rd law

 For every action, there is an equal and opposite reaction.

1. Cross product of two vectors

2. Equilibrium of many-particle system

1. Defition of moment vector

2. Mathematica deduction
   motivation: establish the concept of moment from the requirement of the Newton's laws when applied to many-particle system.

Reference: why the definition of a moment needs a cross product?
