【Abstract】 The flexibility method is taken as the basic principle.This paper develops the technique for precise measuring low-periodic fatigue performance of materials under normal or meidium temperature.The result shows that measurement of low-periodic fatigue performance by applying flexibility method through automatic inspecting the crack length,of which the precision is higher than that by read out through micro- scope.Automatic data proessing is possiblle.This method of measurement especially suitable for precise mea- suring the fatigue performance of materials under high temperature.更多还原
