Investigations of wedge loading using boundary element analyses for model 1 macrocracking in ice / R.W. Marcellus.

Title: Investigations of wedge loading using boundary element analyses for model 1 macrocracking in ice / R.W. Marcellus.
Author(s): Marcellus, R. W.
Date: 1992.
Publisher: New York: American Society of Mechanical Engineers
In: Proceedings of the 11th International Conference on Offshore Mechanics and Arctic Engineering - 1992. Presented ... Calgary, Alberta, Canada, June 7-12, 1992. Vol. 4 - Arctic/polar technology. (1992.),
Abstract: Program for two-dimensional boundary element analysis of problems in linear elastostatics was used to model stable macrocracking (condition where cracks are nucleated and propagate, but do not propagate to free surface) in ice, and to investigate crushing with extrusion failure mode for ice. Different loading scenarios were examined and sensitivity studies were conducted. Results show that wedge-loading scenario may explain portion of variability in local ice loads observed from large- and small-scale measurements. Use of boundary element program facilitated analyses of complex crack propagation problems which were considered non-feasible using other numerical solutions.
