In the paper there were presented test results of energy cumulation of plastic strain in the specimen made of PA7 alluminium alloy under constant - amplitude and programmed loadings. During the tests it was found that the courses of changes of plastic strain energy on the same strain levels both under constant- amplitude and programmed loading were similar. It was shown that value of plastic strain energy cumulated in the material till the fatigue failure is not constans and decreases with the increase of fatigue life.
