摘要: Abstract The paper concerns application of the energy parameter, being a sum elastic and plastic strain density in critical plane, for describing experimental data obtained fatigue tests 35NCD16 steel, subjected to constant amplitude tension-compression, torsion variable combined proportional tension with torsion. It has been shown that normal plane is suitable parameter correlation lives steel under considered kinds loading. where reaches its maximum value.
