1st Discussion – Course Application AY2015/2016

Course Application. It is recommended to identify modules that is useful to my own research field. Taking up modules from CE is also possible since certain modules are related to structural dynamics (i.e. stress and vibration theory). However, it should be noted that not all modules are available at any semester. For AY2015/2016 Semester 1, CE5514 Plate and Shell Structures and CE4257 Linear Finite Element Analysis are the best options with close relation to my research field. As per requirement of NUS, 6 modules are required to be completed as part of the partial degree fulfilment, where two must be ME-related, two of ME6xxx series and two of any courses. With the above CE modules, I will be using up the trump cards. Well, let’s wait for Prof’s advice.

Administrative Concerns. As part of WSHE, it is essential to perform a risk assessment  before the commencement of the candidature. The safety video lasted for about 9 mins in which most of the contents are for biological and chemical students. Noise hazard will most likely be the only risk that I may be facing in the future. Well, this can be easily protected with ear muffler or ear plugs.

A desk is assigned in the same laboratory as my Prof. Not as bad as compared to the impression I had back in NTU, where a foul stench lingers within the room/laboratory of my experimental set-up for FYP. However, lots of work will have to be done to beautify the work area – most probably by loads of papers and books as time passes by.

The Very First Paper!

A seemingly interesting topic was found from the pile of papers consolidated within the booklet from 10th European LS-DYNA Conference.

Titled “Statistical Energy Acoustic for High Frequency Analysis”, the paper shows three simple numerical validations between two different codes from two respective developers. Mechanical properties and objective of each examples are not clearly defined, but predictions show good agreement up to 1 kHz before the results start to show slight deviations.

Points to note:

  • In automobile industry, transmission of noise is mainly due to high frequency panel vibration, where the characteristic of these wavelengths is small with respect to the dimensions of the hull structure.
  • Statistical Energy Analysis is a common approach in tackling noise and vibration issues in hull structures.
