MEASURING DEVICE FOR YOUNG'S MODULUS AND MEASURING METHOD FOR YOUNG'S MODULUS

摘要

PURPOSE: To measure Young's modulus simply and accurately concerning a Young's modulus measuring device and a Young's modulus measuring method suitable for the measurement of paper sheets. ;CONSTITUTION: A paper sheet 20 is supported as cantilever-like by a paper sheet mount 21 and a presser plate 22. A load is applied to the paper sheet 20 by a load applying means composed of a Z axis stage 25, a load cell 24, and a load applying portion 23, and the applied load is detected by the load cell 24. Deflection amount at an assigned position of an object to be measured is detected by an X axis stage 28, and a laser displacement gauge 27. The Young's modulus of the paper sheet 20 is obtained based on the applied load and the deflection amount.;COPYRIGHT: (C)1994,JPO&Japio
