A Study on Material Properties of Sealed Rubber Cylinder for Compressible Packer

摘要

The stress-strain curve of the packer seal rubber cylinder material is obtained by uniaxial tensile test in this paper, and the material constants of the Yeoh model is fitted in Origin. During the test, two kinds of samples are tested, the side and intermediate cylinder, and two sets of figures are measured for each sample, totally four sets of data are obtained. By the fitting results of the side and middle cylinder are achieved by comparing the material constants for each sample respectively.
