Abstract
This paper gives the description of an automatic and programmable device especially designed for the analysis of the mechanical properties (dynamic modulus of elasticity, creep and stress relaxation) of samples under light loads. This microprocessor controlled device is a torsion pendulum operating in forced oscillations in the very low frequency domain (V.L.F. : 10-5-1Hz) Its characteristics are compared with those of other existing equipements and some typical results illustrate the operating range of this pendulum. This set up can be associated to a viscoelasticimeter working in tension-compression, shear, flexion, in the range 7.8 Hz - 1000 Hz.
