The work discussed outlines the development of a technique to predict fatigue failure of rubber components under repeated complex stressing. A fracture mechanics approach is adopted, which has been shown to work with simple plane stress type geometries in the past. Real components with three dimensional loading and geometry can be examined with the use of finite element analysis techniques. This allows an estimate of the tearing energy or energy release rate to be made. With a knowledge of the materialís crack growth characteristics it should be possible to predict the rate of crack propagation and estimate the componentís fatigue life. This now allows us to investigate real fracture type problems to large strain deformations.
