An Evaluation of Microstructural Processes Affecting Saline Ice Properties

9312621布朗本研究的目的是发展一个更完整的了解盐冰的主要特征，可用于描述盐冰相对于纯冰的力学行为。这项研究是以前的国家科学基金会资助的延续，该资助显示了盐冰和非盐冰单晶之间的材料强度的数量级差异，以及模量和流动应力之间的较小差异。在这项研究的继续几种可能的微观结构机制将被认为是解释这些差异，结合成一个单一的本构方程盐冰单晶。这项工作的重要性是基于需要更好地了解微观空腔及其在固体材料变形中所起的作用 *

9312621 Brown The objective of this research is the development of a more complete understanding of the dominant characteristics of saline ice that can be used to describe the mechanical behavior of saline ice relative to pure ice. This research is a continuation of a previous National Science Foundation grant which showed an order of magnitude difference in the material strength between saline ice and nonsaline ice single crystals and smaller differences between the moduli and flow stresses. In the continuation of this research several possible micro structural mechanisms will be considered to explain these differences, to be combined into a single constitutive equation for saline ice single crystals. The importance of this work is based on the need for a better understanding of microscopic cavities and the role they play in the deformation of solid materials ***
