One of the major problems in track pad performance and expected life is heat generation brought about by the periodic loading of the pads and their viscoelastic partly dissipative nature. This problem has been simulated numerically making use of a number of simplifying assumptions. The results are included in this final report. We are currently investigating experimentally each of the material variables for a given number ofmodel elastomers and are conducting heat generation experiments with these elastomers during cyclic shear deformations. The experimental results will be used to improve our simulation model for heat generation. A second problem which we feel is important in connection with track pad life and performance is the structural uniformity of the pads achieved during manufacturing. We are embarking on an investigation of the problem of the effects of material, process and geometric variables during injection mold curing. Our initial efforts are numerical having a goal the prediction of crosslink density as function of space and time during the molding process.
