Abstract
For more accurate load measurement, a load measuring arrangement includes a test object and a load measuring device for measuring a load on the test object. The load measuring device includes at least one magnetic field detection device for detecting a magnetic field parameter changing due to load at a measuring zone of the test object. The test object is work-hardened, at least at the measuring zone and at least in a near-surface region extending from a surface facing the magnetic field detection device to a depth of 20 μm, in such a way that it has a dislocation density of at least 5e8/cmand/or a residual stress of at least 400 MPa in amount.
