Polymer Mechanics Aims and scope

Abstract

The possibility of applying the methods of the theory of random processes in order to predict creep in polymer materials of the rheologically simple type under random transient stress is established. The transient random stress is simulated by a one-dimensional Gauss process with zero mathematical expectation and a transient dispersion. Creep is predicted under these conditions by using an electronic computer and adducing experimental data derived from the uniaxial elongation of a woven epoxyphenol glass plastic at an angle of 45° to the reinforcement axes.
