The deformation and failure behavior of materials, joints and components are highly dependent on the strain rate. By means of the high-speed camera system, reliable characteristic values for material characterization and simulation can be determined in high-speed tensile and shear tests. The main objective is the highly accurate determination of strain fields in tests with moderate strain rates, as well as the determination with sufficient resolution in high-speed tests. With the help of the proposed system, dynamic deformation and failure properties can be precisely characterized with regard to service safety and economic efficiency. The focus is on the better understanding of the process-structure-property-relationships which enable an application-specific and property-enhanced manufacturing. In cooperation with the available high-speed testing system, the camera system will be used in ongoing and planned research projects, as well as in student works and practical courses.

材料、接头和构件的变形和破坏行为高度依赖于应变速率。借助高速摄像系统，可以在高速拉伸和剪切试验中确定用于材料表征和模拟的可靠特征值。其主要目标是在中等应变率的测试中高精度地确定应变场，以及在高速测试中以足够的分辨率确定应变场。借助该系统，可以精确地描述动态变形和失效特性，从而提高使用安全性和经济性。重点是更好地理解过程-结构-性能-关系，从而实现特定应用和性能增强的制造。与现有的高速测试系统合作，该相机系统将用于正在进行的和计划的研究项目以及学生作品和实践课程。
