Claim Text:
1. A test system for dynamically and/or cyclically load testing a sample, comprising: a test frame to which a bearing and a counter bearing are attached, the test frame including at least one actuator including a solid state transducer material system coupled to the counter bearing, a fastener coupled to the at least one actuator for holding one end of the sample and for holding another end of the sample which is coupled to the bearing so that the at least one actuator introduces dynamic and/or cyclical mechanical loads into the sample, which act along a load path extending longitudinally between the bearing and the counter bearing through the sample; and wherein the test frame comprises at least a first and second frame part joined together detachably to form a capsule, the first frame part at least partially encasing the at least one actuator and is connected to the at least one actuator by the counter bearing and the second frame part projects above the first frame part, has a dome and is provided with at least one recess oriented laterally to the load path in which the bearing is mounted longitudinally with respect to the load path; and supports are attached to the test frame with each support on a bearing attached to a support structure; and wherein the capsule has a longitudinal axis which is vertically oriented, in at least a longitudinal section through the capsule, the second frame part has a vertically flared outer contour defining the dome, the first frame part has an outer contour with a cross-section tapering vertically downwardly in the longitudinal direction and the second frame part is aligned flush with the first frame part in an area of the largest cross-section of the capsule.
