What does shear strain refer to?
The shear strain is the isolator lateral deformation divided by the rubber height. Design shear strains are up to 250%. DIS has tested isolators to more than 400% shear strain. At that strain each layer of rubber is deformed laterally to four times its thickness. The extreme shear strains in research tests are a testament to the superior manufacturing processes and compounds developed by DIS and provide the isolator with reserve capacity.
