荷重速度一定試験における防振ゴムの力学的挙動

Previously Sawaragi and Tokumaru proposed a fundamental stress-strain relation of materials having hereditary characteristics. In this paper, we investigated experimentally the behaviour of some rubber vibration absorbers and presented experimental evidences that how reasonablly the mechanical behaviour of such visco-elastic materials is explained by this formula. As the behaviour of these materials is complex, we took a test procedure of the constant rate of loading. We obtained the distribution functions of retardation time and hysteresis stress which characterize the behaviour of vulcanized rubbers and discussed their relative significance.
