A framework incorporating dynamic crack propagation and continuum mechanics for modeling ice-structure interaction processes is developed. The framework is build upon a comprehensive review of recent developments in the analysis of dynamic fragmentation problems for materials such as ceramics, concrete, and metals. A review of alternative crack propagation modeling methods is also included in order to illustrate how the developed framework may overcome the shortcomings of existing techniques. This is the first paper (Part I) in a series of three papers. The formulation of the framework is presented in this paper. In the second paper (Part II), implementation of the framework will be described. The application of the framework to various ice-structure interaction problems will be presented in Part III along with the demonstration and investigation of important aspects of these scenarios.

Crack Propagation Velocity

AbstractTensile tests on notched plates of single-crystalline silicon were carried out at high overloads. Cracks were forced to propagate on {110} planes in a <110> direction. The dynamics of the fracture process was measured using the potential drop technique and correlated with the fracture surface morphology. Crack propagation velocity did not exceed a terminal velocity of v = 3800 m/s, which corresponds to 83%7 of the Rayleigh wave velocity vR. Specimens fractured at low stresses exhibited crystallographic cleavage whereas a transition from mirror-like smooth regions to rougher hackle zones was observed in case of the specimens fractured at high stresses. Inspection of the mirror zone at high magnification revealed a deviation of the {110} plane onto {111} crystallographic facets.
