Servo-hydraulic testing machine

申请人目前和计划的研究内容包括纤维复合材料和金属的循环材料行为的实验表征和数值模拟。除了低周和高周区域的循环变形和疲劳行为外，重点还在于循环载荷下的裂纹扩展行为。在这些领域，申请人目前面临的测试可能性和能力不足。这里申请的伺服液压万能试验机旨在扩大申请人的测试范围，从而支持当前和计划中的研究项目的实现。除了确定特征值之外， 在实验室样品上，测试装置中组件的周期性变形和疲劳行为也应该是可测量的。纤维复合材料领域目前和计划的研究重点也集中在提高工作温度下的材料行为上，这解释了测试系统的扩展，包括用于高温下研究的气候室。根据要求列表，本申请信中比较了三种可能的测试系统，然后选择了一种测试系统。

The current and planned research content of the applicants includes the experimental characterization and numerical simulation of the cyclical material behavior of fiber composites and metals. In addition to the cyclic deformation and fatigue behavior in the Low-Cycle and High-Cylce-Area, the focus is also on the crack propagation behavior under cyclic loads. In these areas, the applicants are currently exposed to a deficient testing possibility and capacity. The servo-hydraulic universal testing machine applied for here is intended to expand the testing spectrum of the applicants and thus support the realisation of current and planned research projects. In addition to determining the characteristic values ​​on laboratory samples, the cyclical deformation and fatigue behavior of components in the test setup should also be measurable. The current and planned research priorities in the field of fiber composites also concentrate on the material behavior under increased operating temperatures, which explains the expansion of the test system to include a climatic chamber for investigations under elevated temperatures. On the basis of the list of requirements, three possible test systems are compared in this application letter and then one test system is favored.
