Abstract

The paper presents a microdefects closure effect at the direct tension and feedback compression (stress control test and strain control test ). It should be noted that low-plasticity materials microdefects closure parameter rates less than the high-plastic materials. The resulting method of determining the microdefects closure parameter at direct tension and feedback compression; obtained the experimental results of determining the microdefects closure parameter of structural materials - D16T, 30KhGSA steel, 45 steel, copper, steel 12X18H10T. A generalization of the curves for the determination of the microdefects closure parameter for the elastic-plastic tensile and feedback compression to plastic materials with different properties.
