Study on the Properties of Compressive Strength of Sea Ice and Fresh Water Ice

Abstract

It is very important to know the precice compressive strength of sea ice in order to estimate ice force acting on marine structures. This study aims to estimate the uniaxial compressive strength of sea ice and fresh water ice.
The authors carried out systematic experiment on uniaxial compressive test and dynamic elastic modulus measurement of ice. Finally, compressive strength and static elastic modulus of ice depend on ice temparature and density, and is clarified that they can be estimated by using a dynamic elastic modulus.
