The behavior of the LDRB isolators is highly linear in shear stiffness and the damping ratio is 2 - 3% of critical damping. There is no creep in the material and the stability of the modulus of elasticity is very good. Advantages of LRDB insulators; they can be modulated in a simpleway and they are less affected by the factors that have mechanical behaviors. These insulators may need additional damping elements.
