Measuring Systems | ARAMIS | Applications | Material Testing | Material Analysis | | | | | Advanced optical High-Speed testing: Investigations of materials and components utilizing High-Speed cameras | |  | | | | Measuring Systems: ARAMIS, PONTOS | | | | Keywords: High-Speed Tensile test, crash, drop test, cell phone, machine tool, process optimization | | | | When determining material characteristics, optical measuring techniques provide a larger validity range, particularly with respect to plastic deformation. Higher demands on crash safety in the automotive industry and on the dynamic behavior of other products require high-speed optical solutions because there, no sensor technology is exposed to the high speeds or accelerations. |  | |
| | Riveted joint under load | |  | | | | Measuring Systems: ARAMIS | | | | Keywords: bonded specimen, load transfer | | | | Rivets are proven to join aluminum sheets or fasten them to the support structure in light weight constructions. This application note shows a simple test set-up, consisting of two aluminum sheets, joined together using three rows of rivets. | | |
| | Optical Deformation & Strain Measurement in Biomechanics | |  | | | | Measuring Systems: ARAMIS | | | | Keywords: biomechanics, digital image correlation | | | | Biomechanics place huge challenges on existing measurement technologies for determining the mechanical properties of these materials, as well as just measuring the full-field displacement and strain of these materials. 3D Image Correlation Photogrammetry is proving to be a powerful tool for these measurements, providing fullfield 3D measurement of the specimens under normal loadings, even at high-speed. | | |
| | Advanced Photogrammetry For Robust Deformation And Strain Measurement | |  | | | | Measuring Systems: ARAMIS | | | | Keywords: digital image correlation | | | | Full-field optical measuring techniques are finding increasing use in industry as development and design tools.
Techniques such as moiré and holographic interferometry,
speckle and ESPI have been thoroughly described from the
theoretical perspective as well as the application engineering viewpoint. This paper describes a deformation measurement technique that has received much less attention than the laser-based methods mentioned above, but which deserves a lot more. | | |
