Shear strength tests on structural parts made by seaming, for example lap welded, riveted, screwed or glued, are generally carried out on tensile test specimens. In this case, the ends of the specimen are clamped in a tensile testing machine and the seamed composite is exposed to a tensile force. This tensile force creates shear stress at the joint.

生ずる。 However, this type of test has various drawbacks. In other words, a tensile specimen consisting of, for example, two sheet metal parts screwed or riveted together and tensioned on both sides, tends to tilt in the tensioned state. The same thing occurs with specimens that are glued or flat welded or brazed. This results in a superposition of shear, bending and tensile stresses which is undesirable for accurate shear strength measurements and strain detection.

Device according to claim 1, characterized in that the guide elements 3, 4 have a sliding guide device or a rolling guide device GR. 3. Device according to claim 1, characterized in that the guide element consists of a dovetail guide (14). 4. The dovetail guides 14 in both receiving elements 1, 2 have an interruption which allows the receiving elements 1, 2 to come into contact with each other in the inserted state of the test piece 13 and then move into the test position. 4. A device according to claim 3, characterized in that the device is arranged to allow the 5. Claims 1 to 4, characterized in that the recesses 7, 8 have replaceable inserts 9, 10, in which the test piece 13 can be accommodated and supported. A device according to any one of the above. 6 Substrate 1 on which the test piece 13 can be fixed or adjusted
6. Device according to claim 1, characterized in that it can be fixed in position relative to the shear plane SE by spacer plates 6, 17 or by spacer plates 11, 12. 7 Substrates 16, 17 or spacer plates 11, 1
7. Device according to claim 6, characterized in that 2 is adjustable from the outside of the receiving elements 1, 2. 8 At least one receiving element 1, 2 has a through opening 18, 18' which is arranged running parallel or perpendicular to the shear plane SE, Claims 1 to 7, characterized in that a support element for supporting the end face side or nests 9, 10 for accommodating and supporting the test piece 13 can be fitted therein. The device described.
