Using the results of laboratory experiments on thermomechanical behaviour of natural ice, the origination and evolution of induced anisotropy observed in ice cores of Greenland (GRIP, GISP2, North GRIP) and Antarctica (Vostoc, DOME-C, DOME-FUDJI, EPICA) have to be modelled. A theoretical continuum mechanical model, as well as numerical algorithms appropriate for simulation of recrystallization dynamics will be developed. The model will be applied for improved calculation of ice sheet dynamcis to obtain a realistic prediction of ice sheets flow.

利用天然冰热力学行为的实验室实验结果，必须模拟在格陵兰岛(GRIP，GISP2，北极洲)和南极洲(Vostoc，Dome-C，Dome-FUDJI，EPICA)冰芯中观察到的诱导各向异性的起源和演化。建立了理论上的连续介质力学模型，以及适用于再结晶动力学模拟的数值算法。该模型将被应用于改进的冰盖动力计算，以获得对冰盖流动的真实预测。
