The presented study focuses on measuring volume changes in elastomeric materials using digital image correlation (DIC), specifically the 2D DIC universal system and video-extensometer directly implemented to testing machine. Optical measurement methods were applied two-dimensional (2D) configurations during mechanical of dumbbell-shaped test specimens under uniaxial tension. measured data used ...
Articular stress fracture arising from the distal end of the third metacarpal bone (MC3) is a common serious injury in Thoroughbred racehorses. Currently, there is no method for predicting fracture risk clinically. We describe an ex-vivo biomechanical model in which we measured subchondral crack micromotion under compressive loading that modeled high speed running. Using this model, we determin...
Geotechnical monitoring and instrumentation are indispensable parts of the Observational Approach. in tunnel design construction. They an essential requirement for a proper risk management. Since 2013 several standards, valid both Europe under CEN international ISO, were developed dealing with geotechnical monitoring. Five standards have been published by 2020, covering general rules, extensome...
Currently, research on structural health monitoring systems is focused on direct integration of the system into a component or structure. The latter results in a so-called smart structure. One example of a smart structure is a component with integrated strain sensing for continuous load monitoring. Additive manufacturing, or 3D printing, now also enables such integration of functions inside com...
This work presents a low cost (∼$500) fully customizable tensile tester, together with custom made operation software. It delivers data of similar quality to commercial equipment.
