Abstract:
A method to predict and/or control the strength properties of a foil-like material in relation to machinery and processes for manufacturing this material. The measurements are performed locally on the foil-like material and with a high spatial resolution - from 20 mm and less - to obtain a mean value and variation regarding at least one local mechanical property of the foil-like material, whereby the strength value or control signal worked out from the measurement results obtained is used to achieve the strength prediction and/or the process and quality control desired.
