Materials testing apparatus for measuring tensile strength of very thin layers

摘要

The material test apparatus (1) has a pair of torsion bars (4), which act as the flexible holding part of the swivel lever (3). A frame (5) serves as the rigid holding part for the test specimen (2). The mechanical characteristics of which are measured, by the application of a single axis tensional force, achieved by applying a vertical load (W) at one end of a swivel lever. The specimen (2) is designed as a one piece unit with the frame (5) and the swivel lever (3). So that the values of the mechanical characteristics can be easily measured, without a direct contact with the test specimen (2).
