Record #126913:

Dynamic analysis of the medium scale hydraulic ice indentation apparatus / Paul A. Spencer, D.M. Masterson.

Title: Dynamic analysis of the medium scale hydraulic ice indentation apparatus / Paul A. Spencer, D.M. Masterson.
Author(s): Spencer, Paul A.
Masterson, D. M.
Date: 1993.
Publisher: New York: American Society of Mechanical Engineers
In: OMAE 1993. Proceedings of the 12th International Conference on Offshore Mechanics and Arctic Engineering. Volume IV. Arctic/Polar technology. (1993.),
Abstract: Apparatus described here has been used in four studies conducted in Canadian Arctic, and has applied loads of up to 12 MN at speeds of up to 400 mm s⁻¹. Numerical model of apparatus has been constructed, which includes servo valve, servo control loop, indenter mass plus foundation stiffness and damping. Main conclusion is that characteristic sawtooth load--time waveforms are caused by ice failure and not by servo-loop characteristics. Observed and calculated system stiffness values are in good agreement.
