摘要： A hand-held lift loop assembly tester apparatus and method tests peel strength of a heat seal connection between a lift loop patch and a bulk bag body as an indicator of shear strength of the connection and whether the bag will pass industry safety lifting requirements. A lifting platform of the hand loop tester is inserted between the patch and the bag body in an unsealed area and measures the amount of peel and thus the peel strength of the heat seal bond or connection at the edges or sides of the unsealed area. If the peel strength is adequate, this is a reliable indicator that the shear strength of the bond or connection is also adequate and that the bag will meet the current industry required 5 to 1 safety lifting requirements.

摘要： An apparatus for testing a sheet of brittle material is disclosed. The apparatus can include a plurality of assemblies configured for selectively applying a 3-point bending load on an edge of the sheet of material in a test region of the apparatus, a detection mechanism that optically measures strain in the sheet of material in the region, and a processor that determines the stress in the sheet based on the measured strain by calculating the stress that would be required to produce the measured strain in the sheet of material.

摘要： A measuring device for detecting measuring signals during either a scanning across a surface to determine a surface profile or a penetration movement of an indenter into a surface of the specimen to determine hardness, and, scanning with sufficient force to determine the scratch resistance of the specimen is described. All of the measurements can be done on the same specimen without unmounting the specimen from a holder. A camera mounted to the same framework as the measuring device enables further documentation of the specimen being tested.

摘要： Disclosed are a rolling test device and a rolling test method. The rolling test device includes a test platform having a rolling surface for placing a test piece to be rolled; a rolling jig located on one side of the rolling surface; and a driving member connected to the rolling jig. A roller is connected to one end of the rolling jig towards the rolling surface, and after the roller is pressed against the rolling surface, the driving member drives the rolling jig to move on the rolling surface to drive the roller to perform a rolling test on the rolling surface.

摘要： Apparatus and methods for impact testing of a transparent substrate are provided. The apparatus includes a base (110) for receiving the transparent substrate (112), the base having a curved surface (124) about which the transparent substrate is bent by a first fixture (130) and a second fixture (132). An abrasive sheet (136) is disposed between the transparent substrate and an impacting object (138) which is released from above the substrate such that the force from the impacting object causes damage to the transparent substrate while the transparent substrate is bent about the curved surface.

摘要： Method for characterizing a material (10), characterized in that it comprises the steps of carrying out a bending test and calculating a cross-section moment, M of said material (10) using the following equation: M = F · L m ( β 1 ) 2 · cos 2 ( β 1 ) where F is the applied bending force, Lm (β1) is the moment arm, and β1 is the bending angle. The expression for the moment, M, fulfils the condition for energy equilibrium: ∫Fds=f2Mdβ2 when the true bending angle, β2 is: β 1 - ∫ t · sin ( β 1 ) L m d β 1 .

摘要： A method for bending test of a flexible screen is disclosed, including: connecting the flexible screen to a fixing device to form two connection ends; and conducting an extrusion test to the flexible screen, including moving the fixing device to change the distance between the connection ends of the fixing device so that the distance is less than or equal to the length of the flexible screen between the two connection ends. A system for bending test of a flexible screen is also disclosed. The above method and system for bending test of a flexible screen, which can simulate an operational environment of the flexible screen by moving the fixing device to conduct an extrusion test to the flexible screen, can reduce testing costs compared with the traditional methods and apparatuses for bending test of a flexible screen.
