MARC recordThe size effect of nominal ice failure pressure, fractals, self similarity, and nonstationarity / B.L. Parsons.
| Title: | The size effect of nominal ice failure pressure, fractals, self similarity, and nonstationarity / B.L. Parsons. |
| Author(s): | Parsons, B. L. |
| Date: | 1991. |
| Publisher: | St. John's, Newfoundland: Memorial University of Newfoundland, Ocean Engineering Research Centre |
| In: | POAC'91 : the 11th International Conference on Port and Ocean Engineering under Arctic Conditions, September 24-28, 1991, St. John's, Canada. (1991.), Vol.1. |
| Abstract: | Pressure/area curve shows that observed ice-failure pressure is proportional to inverse square root of loaded area. Two recent heuristic models for explaining this are compared and found to be modelling same roughness profile, self-similar surface of fractal dimension 1,5, with nonstationary root mean square roughness proportional to L¹/². Scale effect is alternately explained by means of load-sharing mechanism (Bhat 1990) and nonstationarity (Parsons 1990). Modification of load-sharing mechanism is shown to be necessary in light of nonstationarity of profile. |
