Viscoelastic coefficient measuring method, viscoelastic coefficient measuring apparatus and program

摘要

Problem to be solved: to provide a viscoelastic coefficient measuring method, a viscoelastic coefficient measuring apparatus and a program capable of obtaining a viscosity coefficient and an elastic coefficient of a substance in a simple and high-speed manner.Viscoelastic modulus measuring methodModifying the sample SP1 over timeWhen the sample Sp1 is deformed in time, the history of the indentation amount of the indenter 15 and the history of the press load acting on the indenter 15 are obtained andIndentation δ Based on the history ofCalculate the history of the indentation rate andViscosity and elastic modulus of sample Sp1 and indentation δ Using a relational expression describing the relationship between the indentation load and the indentation rate.Indentation δ An approximate solution of the viscosity coefficient and an approximate solution of the elastic modulus are calculated from the history of the history and the history of the indentation load and the history of the indentation rate..Diagram
