Abstract

Experimental data are reported on isotactic polypropylene in uniaxial tensile cyclic tests with stress- and strain-controlled programs. A constitutive model is developed that adequately describes stress-strain diagrams, and its parameters are found by fitting the observations. Numerical simulation demonstrates that fatigue failure in ratcheting tests is induced by pronounced growth of plastic strain in crystallites.
