A testing apparatus for a flexible screen includes a slide rail, a reel, and a clamping member. The reel is disposed at an end of the slide rail in the extension direction of the slide rail which the axial direction of the reel is perpendicular to. The reel has a hollow structure and is connected to a evacuating device through a gas path formed in the hollow structure to enable the evacuating device to vacuumize inside of the reel to fit the flexible screen and coil around the reel. The reel is configured to affix first end of flexible screen and rotate to coil the flexible screen. The clamping member is configured to clamp a second end of the flexible screen opposite to the first end. The reel is further configured to rotate to drive, through the flexible screen, the reel and the clamping member to slide towards each other along the slide rail.

An in-situ testing equipment for testing micromechanical properties of a material in a multi-load and multi-physical field coupled condition is disclosed. The equipment comprises a frame supporting module, a tension/compression-low cycle fatigue module, a torsioning module (21), a three-point bending module (6), an impressing module (33), a thermal field and magnetic field application module (34), an in-situ observation module (32) and a clamp body module (22).

A method for testing the strength of a sheet-like element having two opposite faces and made of hard brittle material under tensile stress is provided. The method includes passing each of the faces of the element over a roller and thereby bending the element so that each of the faces is subjected to a first tensile stress in a portion in which the opposite face is in contact with a surface of the roller; exerting a second tensile force on the element in the direction of advancement so that both faces are subjected to the second tensile stress of at least 2 MPa so that the first and second tensile stresses add up to define a resultant tensile stress; and monitoring the element and determining whether the element has a defined breaking strength equal to the resultant tensile stress or whether the element breaks under the resultant tensile stress.
