Abstract

For CP type creep-fatigue test life prediction,a numerical computational method was proposed by author,namely,in order to obtain parameters Xi(i=1,4) of prediction equation N-1=(σT·Δεp)x2/x1+(σT·Δεc)x3/x4,optimizing approach of parameters was adopted.Thus,it not only can save cost and simplify test procedure,but also proves that the numerical computational method of SEP is better than the current SEP method in prediction accuracy and prediction capacity.
