Benchmark Bending Test of a Thick Specimen. Part 2. - Surface DisplacementMeasurements

摘要

An experiment has been undertaken to provide benchmark data for validatingmethods of calculating the plastic behavior of metals. In this experiment a 30 mm square-test-section specimen of 7050-T7451 aluminum alloy has been loaded in four-point bending, and the surface distortions of all four faces have been measured with the aid of a square grid pattern imposed on the surfaces before deformation. Part I of the Report describes the experimental details and gives the results of the material property tests, thus providing sufficient information for the prediction of surface displacements. This part of the Report gives the displacements measured and describes the various manipulation and averaging procedures used with the data to put them in a form suitable for comparison with predictions....
