Abstract
The stress-strain curve of the packer seal rubber cylinder material is obtained by uniaxial tensile test in this paper,and the material constant of the Yeoh model is fitted in Origin.Two kinds of samples are tested,the side and intermediate cylinder,and two sets of figures are measured for each sample,totally 4 sets of data are obtained.Finally,by comparing the material constants for each sample respectively,the fitting results of the side and middle cylinder are obtained.关键词
