New developments based on the optical measurement technology allow for a full-field analysis of the 3D deformation behavior of tires tested under extreme conditions on a special setup. This application example examines the behavior of a tire side wall with large slip angles and presents the visual results. |  | |
| | Advanced optical High-Speed testing: Investigations of materials and components utilizing High-Speed cameras | |  | | | | Meetsystemen: 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. | | |

The technique is also broadly applicable for air blast deformation measurements, crash testing, high strain rate testing, and other dynamic phenomena. | | |
| | Full-field dynamic deformation and strain measurements using high-speed digital cameras | |  | | | | Meetsystemen: ARAMIS | | | | Keywords: 3D image correlation, digital high-speed photography, impact testing, LS-DYNA, dynamic strain, full-field, gas gun, reinforced carbon-carbon | | | | Digital cameras are rapidly supplanting film, even for very high speed and ultra high-speed applications. The benefits of these cameras, particularly CMOS versions, are well appreciated. This paper describes how a pair of synchronized digital high-speed cameras can provide full-field dynamic deformation, shape and strain information, through a process known as 3D image correlation photogrammetry. The data is equivalent to thousands of non-contact x-y-z extensometers and strain rosettes, as well as instant non-contact CMM shape measurement. A typical data acquisition rate is 27,000 frames per second, with displacement accuracy on the order of 25-50 microns, and strain accuracy of 250-500 microstrain. | | |

the robust measuring principles. The power of image
correlation provides superior dynamic range and ease of use
for many test situations. In combination with pulsed
