This project will measure the uniaxial compressive stress- strain relationship of a suite of cemented tungsten-carbide samples. Because of its high strength, cemented tungsten carbide is used as a key structural component in the design of state-of- the-art high pressure multi-anvil apparatus capable of experimentation up to 25-30 GPa. Optimal design of high-pressure apparatus is hampered by a lack of information about the fundamental rheology of this material under conditions that mimic the conditions imposed on the material in such high-pressure systems. This project is intended to provide the necessary data, and the results will also enable finite element analysis of new designs for improved high-pressure apparatus. Experimental capabilities in the ultra-high range of static pressure are necessary for basic research in earth sciences and materials science.

本项目将测量一套硬质合金样品的单轴压应力-应变关系。由于其高强度，硬质合金被用作设计最先进的高压多砧装置的关键结构部件，该装置的实验强度可达25-30 GPa。在模拟高压系统中施加在材料上的条件下，缺乏关于这种材料的基本流变学的信息，阻碍了高压装置的优化设计。该项目旨在提供必要的数据，其结果也将为改进的高压设备的新设计提供有限元分析。超高静压范围的实验能力是地球科学和材料科学基础研究的必要条件。
