Ice-sheet failure against inclined and conical surfaces
Ice-sheet/structure interation models were prepared and analyzed numerically. The study covers parameters to analyze displacement boundaries, the effects of sharp forward ridges, artificially induced cracks, etc. These variables are difficult and costly to incorporate into experimental work.The floa...
