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.

申请人目前和计划的研究内容包括纤维复合材料和金属循环材料行为的实验表征和数值模拟。除了在低周和高周区域的循环变形和疲劳行为外，还重点研究了循环载荷下的裂纹扩展行为。在这些领域，申请人目前面临着测试可能性和能力不足的问题。这里申请的伺服液压通用试验机旨在扩大申请人的测试范围，从而支持实现当前和计划的研究项目。除了确定实验室样品的特征值外，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中的研究重点也集中在材料在高温下的性能，这解释了测试系统的扩展，包括在高温下进行研究的气候室。根据要求清单，在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。
