拉伸法测量水凝胶弹性模量

In this paper, tensile method is used to measure young's modulus of the hydrogels. The theoretical basis is the hooke's law, which the ratio of stress and strain is the young's modulus of hydrogels. It proved that the measuring range of tensile method is within the applicability of the hooke's law.Hydrogel for known young's modulus was measured by Tensile method, compared with reference,and tested and verified the accuracy of the improved tensile method. It is more accurate for measurement results of tensile method to calculate the buoyancy of weigh. Young's modulus of the different hydrogels were measured by improved tensile method.
