Fracture toughness of fresh water prototype ice and carbamide model ice

Prototype freshwater ice samples as large as 2 cubic metres were tested with the double cantilever beam technique and values for the k(1c) as large as 500kN/m(3/2) were obtained. Samples with vertical prepared crack plane propagating horizontally display the lowest values for k(1c) with a mean of 20...

Description
Summary:Prototype freshwater ice samples as large as 2 cubic metres were tested with the double cantilever beam technique and values for the k(1c) as large as 500kN/m(3/2) were obtained. Samples with vertical prepared crack plane propagating horizontally display the lowest values for k(1c) with a mean of 200kN/m(3/2). The fracture toughness of two layer carbamide ice thickness is thicjness dependent and a quatratic function of flexural strength. Peer reviewed: Yes NRC publication: Yes
