  • Method, device and machine for pure bending test optionally alternating
    Patent number: 7017423
    Abstract: The present invention provides a method, apparatus, and a machine for testing in pure bending, optionally in alternating bending. Two mutually identical testpieces are subjected to optionally alternating opposing bending movements while conserving mutual symmetry about a point, under drive from two controlled motor assemblies that are free to move relative to each other. Interfering forces induced in the two testpieces during testing are minimized, and the performance of the testpieces in pure bending can be studied with increased accuracy.

  • Method, device and machine for pure bending test optionally alternating
    Publication number: 20050241405
    Abstract: The present invention provides a method, apparatus, and a machine for testing in pure bending, optionally in alternating bending. Two mutually identical testpieces (1) are subjected to optionally alternating opposing bending movements while conserving mutual symmetry about a point (22), under drive from two controlled motor assemblies (21) that are free to move relative to each other. Interfering forces induced in the two testpieces (1) during testing are minimized, and the performance of the testpieces (1) in pure bending can be studied with increased accuracy.
