Abstract

The authors propose a method for testing plastics endurance under plane transverse bending with a given cyclic deformation. The paper describes the relations for the calculation of the amount of deflection, rotation angles of the end parts of a sample and the technological gap d between the pins in movable supports and a model for the transverse bending of a sample, the properties of which are given by linear-elastic and nonlinear elastic (according to power law) models. To determine the dependence of stresses on the number of cycles before sample failure, the authors propose the method for estimating stress with the use of the dependence of stresses on the number of cycles before failure and stress-deformation dependence, obtained in quasi-static tests under "instantaneous" loading.
