Nondestructive testing
Nondestructive testing or Non-destructive testing (NDT) is a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component or system without causing damage.[1] The terms Nondestructive examination (NDE), Nondestructive inspection (NDI), and Nondestructive evaluation (NDE) are also commonly used to describe this technology.[2] Because NDT does not permanently alter the article being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting, and research. Common NDT methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), eddy-current testing,[1] and low coherence interferometry.[3][4] NDT is commonly used in forensic engineering, mechanical engineering, petroleum engineering, electrical engineering, civil engineering, systems engineering, aeronautical engineering, medicine, and art.[1] Innovations in the field of nondestructive testing have had a profound impact on medical imaging, including on echocardiography, medical ultrasonography, and digital radiography.
Methods[edit]
NDT methods may rely upon use of electromagnetic radiation, sound, and inherent properties of materials to examine samples. This includes some kinds of microscopy to examine external surfaces in detail, although sample preparation techniques for metallography, optical microscopy and electron microscopy are generally destructive as the surfaces must be made smooth through polishing or the sample must be electron transparent in thickness. The inside of a sample can be examined with penetrating radiation, such as X-rays, neutrons or terahertz radiation. Sound waves are utilized in the case of ultrasonic testing. Contrast between a defect and the bulk of the sample may be enhanced for visual examination by the unaided eye by using liquids to penetrate fatigue cracks. One method (liquid penetrant testing) involves using dyes, fluorescent or non-fluorescent, in fluids for non-magnetic materials, usually metals. Another commonly used NDT method used on ferrous materials involves the application of fine iron particles (either liquid or dry dust) that are applied to a part while it is in an externally magnetized state (magnetic-particle testing). The particles will be attracted to leakage fields within the test object, and form on the objects surface. Magnetic particle testing can reveal surface & some sub-surface defects within the part. Thermoelectric effect (or use of the Seebeck effect) uses thermal properties of an alloy to quickly and easily characterize many alloys. The chemical test, or chemical spot test method, utilizes application of sensitive chemicals that can indicate the presence of individual alloying elements. Electrochemical methods, such as electrochemical fatigue crack sensors, utilize the tendency of metal structural material to oxidize readily in order to detect progressive damage.
Analyzing and documenting a non-destructive failure mode can also be accomplished using a high-speed camera recording continuously (movie-loop) until the failure is detected. Detecting the failure can be accomplished using a sound detector or stress gauge which produces a signal to trigger the high-speed camera. These high-speed cameras have advanced recording modes to capture some non-destructive failures.[5] After the failure the high-speed camera will stop recording. The capture images can be played back in slow motion showing precisely what happen before, during and after the non-destructive event, image by image.

The DATS (Data Acquisition & Testing Services) OLE test train for the MML has recently had an upgrade - rather than using ROG 47s or 57s sandwiching its 2 ex-LNER 91s (91122 & 91128 "INTERCITY 50") and 8 Mk3a coaches, it now uses ex-EMR 43s 43054 & 43066 for propulsion.
I don't think a formation like this has been seen since BR did tests for an HST-E!
With calibration now ongoing for the train's onboard computer systems, 43066 & 43054 (trailing) scream northwards past Marholm on 3Q23, the 1146 test run from Peterborough Eastfield Junction to Doncaster. Note that the pantographs on 91128 & 91122 are raised for data collection...

High above Mallam in the Yorkshire Dales is this exposed stretch of Limestone pavement with the iconic lone tree.
Stood there on this rather gloomy day I couldn't help but wonder how many stormy windy days this rather gnarled tree had withstood over the years and how many people had stood in the spot I was standing admiring the tenacity of nature.
On the technical side this was taken with a Fuji X-E1 a lowly 12mp camera converted to info red, in the days of high mega pixel cameras this goes to show what 12 mp can still achieve.
Panavia Tornado GR.1P ZA326 at the South Wales Aviation Museum St Athan Glamorgan. Built at BAe Warton Lancashire in 1980 but suffering a engine fire on ground runs soon after. This delayed its first flight until March 1983, damage to the rear of the aircraft was repaired with new components from the production line, later delivered that same year to RAE Bedford for trials work. This continued after a move to A&AEE Boscombe Down Wiltshire in 1994 finally retiring in 2005 after 22 years of flight test work, also as the UK's last airworthy Tornado. Put into store before moving to the Cold War Jets at Bruntingthorpe Leicestershire in 2013 and a potential for fast taxy runs. After this airfield was sold ZA326 then moved to S.W.A.M. in 2018 where work progressed due to inside hangar work on restoration and spares source including two complete engines. This work done by the dedicated volunteers of the Panavia Tornado Preservation Group.
Footnote:- ZA326 was the only Tornado to be painted in the superb 'Raspberry Ripple' colour scheme.
After trying her little jacket on i decided the limbs need to be a little longer...
Mini Coraline is a custom lalaloopsy doll i'm working on. you can see her progress here
First test using Stop Motion Pro.
Making of plastelina figures. Greenscreen.
The hole family to work........
Random scenes. Macro photography.
Loads of fun for young and old........
And sorry to say. I stole sound from "Shaun the sheep".
Hope I am forgiven....................
This is just a test shot to check if my camera is working and if I've inserted film right. I think they retouched my photos in the photo lab which well, sucks.
Shot through the window of a moving vehicle so it is not as sharp as it should be. This is the "classic chrome" setting.
The northbound SMART commuter train waits at San Rafael station for a test run to Solano on June 5, 2017. Shortly, there will be free trips for the public prior to normal service in September, 2017 (estimate).
A weathered farmhouse sits under the milky way near Wasco, OR. It was eerie walking around the property in the pitch black over broken boards and wire. It was deadly silent, except for the occasional creaking sound of a nearby windmill being pushed by a light breeze..
Testing and more testing of the quality of the wine ensures that the consumer is getting only the very best of Australian produced wines.
