Title:
引張り応力の測定方法
Document Type and Number:
Japanese Patent JP5563019
Kind Code:
B2
Abstract:
A tensile testing machine has a jaw which comprises a unitary 'H' section member having a cross piece (25) and two uprights (26). The cross piece is mounted to a cantilever beam which is supported on said test machine and has force measuring elements. A pneumatic actuator (20) applies tensile forces to the first ends of the jaw (23) via strands (22) to urge them apart. When first ends of the uprights are urged apart, their oppositely disposed second ends are urged together to grip a sample deposit (29) to be pulled off a substrate in a tensile test. In use, the jaws can be moved at speed, in the order of 500 mm/s to pull the deposit off of the substrate. The force required to pull the deposit off the substrate in this tensile test is measured by the force measuring elements on the beam (35).
