Deformation of thermoplastic materials at low-cycle loading

Polymer Mechanics Aims and scope

Abstract

The possibility is discussed of deducing analytical equations for evaluating the deformation of polymer materials at a low-cycle periodic loading on the basis of the linear prehistory theory. Finite expressions are given for the case of loading by rectangular and triangular pulses. Comparison of the results of the experimental study of the deformation of low- and high-pressure polyethylenes (LPP and HPP, respectively) with the conclusions of the theory shows satisfactory agreement for tests of up to 5·103 loading cycles.
