THE EFFECT OF TIME AND TEMPERATURE ON THE MECHANICAL BEHAVIOR OF A 'PLASTICIZED' EPOXY RESIN UNDER DIFFERENT LOADING MODES

Abstract

Epoxy-plastic specimens were loaded in tension, compression, and flexure at different strain rates and temperatures to determine mode of failure, yield stress and strain, and tangent and relaxation moduli. Stress-strain curves were used to define brittle, ductile, ductile-rubbery, and rubbery modes of behavior which prevailed in different temperature-strain rate regions. The time- temperature superposition principle was applied to yield stress, initial tangent moduli, and relaxation moduli data for all three types of loading.
