Abstract

A method for the thermomechanical analysis of a sample (P) of a material including (a) controlling the temperature of the sample (P), (b) recording data representative for a length variation (dL) of the sample (P), (c) evaluating the data in order to determine a reversible component (dLrev), (d) calculating a corrected reversible component (dLrev-corr; αrev-corr) and/or of the coefficient of thermal expansion (α).
