Compressive and Shear Analysis of Rubber Block
Compressive and Shear Analysis of Rubber Block

The circular shaped blocks uniformly bulges outward for the applied normal force and the shape change also progressively increased on increasing the magnitude of compressive force. Under the shear force of same magnitude the block shear out from inward to outward direction for the applied force creating an unsymmetrical barreling effect. Thus the rolling motion of the tyre creates a dynamic stress over the tread block and its shape parameter studies would improve the designer for optimizing its performance. Furthermore, this procedure was applied for complicated block shapes and was verified to optimize the tyre design.

The rubber blocks of cylindrical shape shows a symmetric barreling under compression for all loads. When the same approach has been extended to the shear analysis, the barreling effect is high on the direction of the force applied and shown a small barreling on the load free side for a very high shear load. The square block shown almost similar behavior in the compression but it behaved in distinguished way under shear force. The other chosen geometrical rubber blocks behavior will be further well analyzed and reported in the future. It has been inferred that for a same contact area, mass and volumetric properties of the rubber block of different geometrical shapes in compression/shear studies under large compressive strain shows a distinguished behavior.
