Abstract
In the paper, I have brought in a method whereby a body with rheological behaviour is associated to a dynamic-equivalent Kelvin model. The equalization is made so that the forced vibration caused for Kelvin model by a harmonic external impulse is identical to the forced vibration caused in the case of the studied rheological model. It was experimentally determined the elasticity modulus and damping factor for samples with Dammar bio-matrix, reinforced with silk, flax or hemp fabric. Modifying samples dimensions, It was studied the vibrations frequency effect on the studied mechanical properties.
