Engineering Research Equipment Grant in Solid Mechanics

提供了一台伺服液压试验机，用于在高温下对材料进行表征。感兴趣的材料是具有脆性基质的纤维复合材料，如陶瓷、玻璃和碳，以及金属基复合材料。这些材料在高温下的应用需求日益增长--最高可达2000摄氏度--这就产生了对高温下的机械特性的要求。这对测试设备和程序提出了一个具有挑战性的问题。这台机器可以通过增加一个带水冷手柄的高温炉和一个用于材料高温表征的光电引伸仪来进行改进。

A servo-hydraulic testing machine is being provided for characterization of materials at high temperatures. The materials of interest are fiber composites with brittle matrices, such as ceramic, glass and carbon, and metal matrix composites. The increasing need for applications of these materials at high temperatures--up to at least 2000 degrees Centigrade--has created the requirement for mechanical characterization at high temperatures. This poses a challenging problem for testing equipment and procedures. The machine can be modified by addition of a high-temperature furnace with water-cooled grips and an electro-optical extensometer for high-temperature characterization of materials.
