Characterization of the Microstructure and Mechanical Properties in Seasonal Lake and River Ice

This ongoing study focuses on the effects of the microstructure and impurities on the mechanical behavior of both seasonal lake and river ice. Ice was collected yearly over a 4-year period (2001-2004) from the same locations, from Lower Baker Pond, Orford, NH and the Connecticut River near Hanover,...

Description
Summary:This ongoing study focuses on the effects of the microstructure and impurities on the mechanical behavior of both seasonal lake and river ice. Ice was collected yearly over a 4-year period (2001-2004) from the same locations, from Lower Baker Pond, Orford, NH and the Connecticut River near Hanover, NH. Mechanical testing coupled with microstructural analysis of the texture of lake and river ice revealed that fracture models and strengths inferred from test performed on S2 lab ice can be used to provide strength estimates for river ice but their use for lake ice is problematic.
