Development of High Temperature Capability for Rotary Direct Shear Rock Deformation

该合同将支持开发旋转直接剪切岩石变形系统的高温能力。主要的研究重点是获取环境温度高的深度断层/裂缝的知识。高温性能也将允许直接剪切的延性岩石变形研究，允许在非常大的应变下研究流变特性和岩石变形结构的发展。为了增加高温能力，将解决三个主要方面的问题：修改样品夹套，修改样品握把以留出炉子的空间，建造炉子。

This award will support the development of high-temperature capability for a rotary direct shear rock deformation system. The primary research focus is to gain knowledge of faulting/fracture at depth where the ambient temperature is high. High-temperature capability will also allow ductile rock deformation studies of direct shear, permitting investigations of rheological properties and the development of deformation textures in rocks at very large strains. Three principal areas will be addressed to add high- temperature capabilities: modification of the sample jacket, modification of the sample grips to allow space for a furnace, construction of a furnace.
