Effects of Specimen Size and Geometry Effects, Loading Rate and Microstructure on the Tensile Fracture of Saline Ice.
This report contains the details of the experimental program on large-scale in-situ arctic sea ice tests. A total of six field trips were completed. The experiments conducted included flexure tests, fracture tests as well as tests where the ice specimen was subjected to cyclic and creep-recovery typ...
