Dynamic mechanical behaviour of filled and unfilled elastomers under uniaxial and multi-axial conditions

Various methods for multi-axial testing of elastomeric materials are reviewed. The principles and performance characteristics of a purpose-built test apparatus are described which applies (multi-axially) dynamics and approximately homogeneous strains to a elastomeric testpiece. Experimental data on a range of elastomeric materials are presented for experiments performed with rotating and non-rotating principal axes. Patterns of behaviour regarding cycle-cycle changes and quasi-equilibrated behaviour will be outlined giving guidance for correct three-dimensional modelling.
