Digital image correlation (DIC) has become an industry staple quickly replacing classic techniques. High-speed images are taken of a material sample being deformed, then algorithms applied to calculate variables of sample deformation such as stress, strain, displacement and displacement velocity. Currently, the analysis technology is not available at the level of simplicity and accessibility needed to teach the methods in an undergraduate laboratory. This project aims to develop a single program to perform DIC that is simple to use, accurate, and available at low cost. This paper describes the state of current DIC algorithm research, drawbacks of available technologies, the development cycle of the software including the techniques used to obtain the necessary accuracy and performance, and a demonstration of the DIC functionality in comparison to results obtained from commercial software.

The Cost

Although turbine blade cooling has consistently led to the use of higher turbine inlet temperatures leading to improved cycle efficiencies, very little of this technology has found its way into undergraduate laboratory work. The cost of modern blade heat transfer research rigs virtually rules out the possibility of introducing this topic in undergraduate teaching laboratories of Universities or Polytechnics in the UK operating within tight budgetary constraints. However, the underlying principles of blade cooling heat transfer may be demonstrated quite easily by using inlet temperatures about half those existing in the actual turbine and the paper describes the design and development of a low-cost blade cooling heat transfer rig. Test results obtained on the ‘model’ rig enable an appreciation of the problems encountered in turbine blade cooling to be made and may serve as a basis for the design and development of more complicated blade cooling systems.

Efforts to bring crystallography into undergraduate laboratories are often hampered by one principal factor: the available funding. The acquisition of instrumentation has always been the stumbling block to establishing a program of crystallography in the undergraduate curriculum. With the introduction of Bruker's D8 QUEST ECO line of diffractometers, new opportunities arise. The ECO line is an all air-cooled set of instrumentation that lowers initial cost, operating cost, and environmental footprint. The system is configured with molybdenum radiation, and, for the first time in a low-cost instrument, with copper radiation. While molybdenum radiation has long been the dominant wavelength, copper allows access to absolute configuration of light-atom molecules. These instruments are fully capable research instruments, allowing for the demonstration and training of the complete experiment, from crystal selection, to selection of experimental parameters, data collection, and structure solution and refinement. Various levels of automation are available to match the needs and abilities of the students, making these instruments versatile through the entire undergraduate program. The transition from this entry-level system to high-end research instrumentation is transparent and undergraduate students will be well prepared for the next steps in their careers.
