Measurement of constitutive properties of a powder specimen subject to compressive axial and radial loading, using eddy current sensing |
摘要 |
A method and system for measuring constitutive properties, such as radial strain, on a specimen of power or other granular material while the specimen is subject to compressive axial and radial loading. The specimen fills a pliable sleeve that has a conductive band around its circumference. An eddy current coil is placed around the sleeve, and used to provide a response signal that indicates the diameter of the sleeve, which in turn indicates radial strain.
