Title:
METHOD AND DEVICE FOR MEASURING VISCOELASTICITY
Document Type and Number:
Japanese Patent JP2021124497
Kind Code:
A
Abstract:
To provide a novel method for measuring a viscoelasticity.SOLUTION: The method for measuring the viscoelasticity of an object includes: the step (A) of applying a pressure (ΔP) generated periodically on an object to cause a deformation in a part of the object and measuring the length (ΔL) of the deformation of the object; the step (B) of calculating ΔP0, ΔL0, and δ from a periodic change of the pressure generated in the step (A) and a periodic change of the deformation length measured in the step (A); and the step (C) of calculating a storage elastic modulus E' and a loss elastic modulus E'' on the basis of the ΔP0, ΔL0, and δ obtained in the step (B).SELECTED DRAWING: Figure 1
