Transcript: Student: Gonzalo Genovart Urra Supervisor: Dr R A Tomlinson Repeat experiments using higher quality and resolution cameras. Not a very realistic option. Repeat experiments with more samples and same equipment. Higher resolution ultrasound in order to better compare the results. Improve painting techniques as paint introduced some noise in the signal. To better understand crack development in Glare validating results with Ultrasound scans. Aerospace Master Thesis Presentation Experiment 2 : Investigating Crack Growth rate on 0º fiber angle To investigate crack behavior in Glare Panels under cyclic loads using Thermoelastic Stress Analysis (TSA) Experiment 1: Effect of Frequency on thermal signal Loading was not large enough to start crack growth. Frequency range between 10-45Hz. Data collected at crack tip singularity and on strain gauge. Data collected several times and averaged. 25x zoom lenses used. Same stress ratio and rest of parameters. Glare What Thermoelastic Stress Analysis is. References  The specimen is painted in matt black to increase emissivity to almost 1. Hot-and-Cold plate calibration method to calibrate pixels on thermographer. Liquid Nitrogen used to increase Signal-to-noise ratio and sensitivity of thermal detector. Orthogonal strain gauges fitted on specimen. Calibration constant calculated previous to experiment. Investigating Fracture and Failure in Aircraft Wing skins Belongs to the fibre metallic laminate (FML) family of composites. Developed by TU Delft in the 1990 to substitute ARALL. Six different grades, This investigation used Glare 3-3/2 . Incredibly fatigue resistant , stiffer and lighter than monolithic Al. 3 layers of aluminium 2000 with 2 double glass fibre layers in between in a 0 ,90 orientation. Increasingly used in Aerospace Industry as a skin covering fuselages and wings. Ultrasound sublayer examination and comparison. TSA is a versatile and easy to use piece of equipment which offer much better resolution than other NDE techniques such as ultrasound scanning. In combination with TSA , FATCAT software is a powerful tool to analyse thermal data and relate this to the LEFM theory. Glare does not follow the Paris Law , " the higher the stress range at the tip the lower the crack growth" As loading Frequency increases the signal strength increases and phase difference decreases. Operation of New Large Aircraft Research. 2013. Operation of New Large Aircraft Research. [ONLINE] Available at: http://www.airporttech.tc.faa.gov/safety/bagot2.asp. [Accessed 10 May 2013]. Previous work on this field?  A 5mm radius semi-circular notch created on the specimen. 2 Glare Panels tested Stress Ratio of 0.4 , with a maximum stress of 190MPa 2 position zoom lenses with a resolution of 14.5px/mm FATCAT software used to analyse data. It was expected to have a crack with decreasing growth rate with cycles. Use TSA to monitor crack growth in different fibre orientations and comparison of results. Question Time. The Aim Experiment 3: Investigating Crack Growth Rate on 90º fiber angle Future work Effect discovered by Weber in 1830s. Similar cause to when heat is emitted in plastic deformation e.g metal rolling, friction within the material similar to hysteresis The intensity of this thermal energy production in elastic regime is lower than in plastic Thermoelastic effect is observed in all materials under cyclic loading conditions Temperature change in the order of thousandths of Kelvin. DeltaTherm 1410 (256x256px) by Stress Photonics, in combination with different thermal lenses Thermal maps are obtained, Thermal signal intensity is directly related to stress. Conclusions The crack is only present in the aluminium layers, not in the fibres Delamination length in the fibre-aluminium interface has a great effect on crack growth. Different TSA techniques have been used such as pulse heating to analyse effect of impact on composite materials. Cyclic loading frequency to be 10Hz or above to have a relatively adiabatic surface. Lock-in thermography can be used at any temperature, used at up to 1200K Experimental setup and Calibration The loading and frequency values were kept the same as in Experiment 2. Same exact notch at the same position as previous test.
Transcript: Main Concerns Introduction Background Information Definitions Agenda Exposed to and target of abuse and discrimination Sunju Yoon 12/19/2014 FTWP is an ongoing issue in Canada Growing number of foreign workers Marginalized status Case study of Temporary Foreign Workers (TFWs) The citizenship boundary faced by foreign workers in South Korea and Canada Since the 1990s TFWPs started, the number of TFWs have rose dramatically groups of people who have set of rights without membership has appeared Access to rights is only available to individuals who hold membership in territorial boundary of citizenship Only possible to acquire through descent or by birth. Principles automatically exclude people whose membership are derived from a different territory Highly visible foreign group Raise knowledge and awareness of issues among FTWs and issues within countries & nations Eligibility? Who can access the rights in the same nation boundary? What makes the different status between resident foreigners and native citizens ? What are better ways to handle this situation? Therefore, I premise citizenship boundary should be re-drawn, reflecting a growing number of residential foreign nations and suggest stakeholder principle from Rainer Baubock as a qualification. He has also re-drawn the boundary of the states as a political community, but in this paper, I did not touch the boundary of political authority and just used the term as “a political community” followed by him. Labour shortage Solution: Import temporary foreign workers from Korea Introduction: Introduction: Why am I doing this work?
