Mechanical uniaxial testing system equipped with quartz lamp heating. The purpose of the testing was not only to compare and contrast the two strain sensors but also to investigate the applicability of the PdCr strain gage to the testing environment typically employed when characterizing the high-temperature mechanical behavior of structural by: 5.

The evaluation of the two strain measurement systems was conducted through the application of various thermal and mechanical loading spectra using a high-temperature thermomechanical uniaxial testing system equipped with quartz lamp by: 5.

National Aeronautics and Space Administration.;]. Comparison Testings between Two High-temperature Strain Measurement Systems. By J An experimental evaluation was conducted at NASA Lewis Research Center to compare and contrast the performance of a newly developed resistance strain gage, the PdCr temperature-compensated wire strain gage, to that of a conventional high-temperature.

During the tensile test the sensor records pictures with a frame rate up to 15 Hz of the investigated specimen. With the Aramis 5M for strain measurements strains in the range from 20 µm/m – µm/m can be measured by the system (GOM b, GOM c). The accuracy up to 10. Randall A. Blue's 6 research works with 43 citations and 75 reads, including: Comparison Testings between Two High-temperature Strain Measurement Systems.

The corresponding results for the 3D system demonstrate that the beam out-of-plane displacement begins to affect the accuracy of the strain measurements at approximately % strain for all magnitudes of out-of-plane displacement, and the 3D ARAMIS system can make accurate strain measurements at up to mm amplitude at this strain.

Finally Author: Niranjan H Desai, Joel R Poling, Gregor Fischer, Christos T Georgakis. In these tests, local deformation at geometrical and metallurgical discontinuities is being monitored directly using pecker capacitance strain gauges. High temperature strain measuring devices with initial gauge lengths of less than 2mm are not widely used, and the choice of suitable sensors worldwide is extremely limited.
