Abstract

The non-linearities of the frame dynamic modulus of elasticity and loss factor of bonded mineral and glass wool materials measured in the range of strain amplitude of 10-6 to 10-2 are reported in this paper. It is shown that the dynamic modulus decreases, and the loss factor increases and passes through a maximum with increasing strain. The measurement technique and the results obtained for the character and the measure of non-linearity, and the linearity limit are given in the paper. An attempt is made to clear up the role of material structure in the non-linear behaviour.
