Abstract
The aim of this work is the derivation of material parameters of polar firn as a function of its density to describe the time-dependent deformation behaviour under compressive stress. The total pressure corresponding to the in situ depths of the firn layer is taken into account. The linear and the nonlinear stress-strain relation will be investigated. The use of simple constitutive equitation to describe settlement measurements in boreholes near the Georg von Neumayer Station in Antarctica yields material parameters to describe the time-independent linear deformation behaviour. Results of uniaxial and triaxial compression and creep tests on "in-situ ice cores" u...
