Abstract
Predicting the Performance of Bonded Filled Rubber Mounts
in Compression Using Data Measured in a Simple Shear Deformation
The problem of predicting the stiffness of
bonded, carbon black filled rubber mounts is difficult because of the problems
associated with geometric non-linearity and material characterisation. It
is proposed that alternative simple forms of stored energy function can
be employed to model the non-linear material properties. For carbon black
filled materials it is apparent that it is possible to obtain the relevant
materials data from just a single materials test made in any of a number
of simple homogeneous deformation modes. The approach is validated by taking
materials data for simple shear measurements and using the data to predict
the behaviour of compression mounts with a range of shape factors.
