As the cable remains line after deformation,according to the deformation compatibility condition (23) we can deduce (24) Substituting (24) and into (6), the horizontal stiffness of isolator can be obtained.From the calculation formulas of stiffness above,we can see,the horizontal stiffness of prestress rubber isolators is not only related to the materials and parameters of isolators,but also related to their vertical loads and horizontal shear.

Introduction Improvement of properties of traditional ceramic materials and creation of new ceramics is impossible without expanding the range and improving the quality of initial powders and changing their chemical composition.
The development of new technologies, principles for the selection of additives contributes to the creation of materials with improved (often unique) physical and technical characteristics, or with a number of special properties.
