A thermomechanical analyzer for efficiently measuring the dynamic viscoelasticity of a sample piece. The analyzer is provided with a function generator, a stress applier, a strain detector, an analog-to-digital converter, a memory and a Fourier transform processor. The function generator generates a sine wave signal to induce a sine wave stress-strain response in the sample piece. This response is Fourier-transformed by the processor to calculate the dynamic viscoelasticity of the sample piece.
