A universal rig for mechanical testing of thin specimens using a novel loading assembly controlled by computer
This paper describes an apparatus which is able to perform tensile true constant stress or strain rate, stress-relaxation and creep tests on a thin strip specimen up to a maximum load of 20 N, in vacuum or in an inert atmosphere and at high temperature. The machine applies the load on the specimen b...
