Fraunhofer Institute for Microstructure of Materials and Systems IMWSThe testing of pull-out forces in component testing refers to the evaluation of a component's resistance to the pull-out of a connection or fastening. This test is particularly relevant for components where the strength of the connection is crucial, such as in screws, rivets, or adhesive bonds. Various methods are used to test pull-out forces in order to determine the maximum tensile force required to loosen the connection or pull out the component.
The following steps can be carried out:
Preparation of the test specimen
The connection is prepared in accordance with the specified requirements to ensure that it is representative of the actual application.
Fastening the test specimen
The test specimen is fastened according to the intended fastening method, whether by screws, rivets, or adhesive.
Applying a tensile force
A tensile force is applied to the test specimen to test the pull-out strength. This can be done using various test methods such as tensile tests, shear tensile tests, or pull-out tests.
Recording and evaluation of results
The tensile force applied is measured and the pull-out resistance of the component is determined. This can be done by recording force-displacement diagrams or by determining the maximum pull-out resistance.
