MARC recordUse of a low-powered laser to measure crack front development / Larry J. Weber, Wilfrid A. Nixon.
| Title: | Use of a low-powered laser to measure crack front development / Larry J. Weber, Wilfrid A. Nixon. |
| Author(s): | Weber, Larry J. Nixon, Wilfrid A. |
| Date: | 1993. |
| Publisher: | Hamburg: Hamburg Ship Model Basin (HSVA), Department for Ice and Environmental Technology |
| In: | POAC 93 : the 12th International Conference on Port and Ocean Engineering under Arctic Conditions, 17.--20. August 1993, Hamburg. (1993.), Vol.1. |
| Abstract: | Describes technique to measure crack growth in fresh-water ice during fatigue tests. Crack growth along entire crack front can be measured by using laser mounted on Vernier slides so that its position is known vertically and horizontally: in this way, "map" of crack front is generated. As crack grows with time, front is mapped out at specific intervals. |
