Young's modulus measurement equipment and measuring method

摘要

PURPOSE:To enable a modulus of elasticity of a development roller to be measured accurately for a device and a method for measuring the modulus of elasticity of an elastic body. CONSTITUTION:The measuring device is constituted by a device 20 for measuring stress - amount of displacement having an upper cell 26 with a projecting portion 27, a lower cell 21 having a recessed portion 22 housing an elastic body 24, a means 29 for detecting an amount of displacement detecting the amount of displacement of the elastic body 24, and a means 25 for detecting stress detecting a stress of the elastic body 24 and an operation means 23 which obtains an amount of distortion according to the amount of displacement which is detected and an initial thickness and then calculates a modulus of elasticity according to the detected stress, thus enabling the modulus of elasticity to be measured.
