AN ATTEMPT TO FORMULATE A THEORY OF CRACK FORMATION IN GLACIERS (VERSUCH EINER THEORIE DER SPALTENBILDUNG IN GLETSCHERN),

Abstract

The plasticity of glacier ice and the relation between the internal deformation of glaciers and fissure formation are investigated on the basis of Somigliana's theory of the mechanics of glacier motion. The forces and strains involved in the deformation of granular ice masses and the resulting fissuring are discussed and analyzed mathematically for glaciers with a linear increase of velocity toward the edges, with a parabolic increase toward the edges and with a constant surface velocity.
