METHOD AND SYSTEM FOR PREDICTING FATIGUE LIFE OF COMPOSITE MATERIAL

WIPO Patent Application WO/2018/107730

A1

A method and a system for predicting a fatigue life of a composite material are provided. The method comprises: performing a tensile property test on a composite material to obtain a tensile stress-strain curve; performing data processing on the tensile stress-strain curve, and mapping the tensile stress-strain curve into a first fatigue life calculation formula for calculating, based on a residual strength of the composite material, a first fatigue life value, and a second fatigue life calculation formula for calculating, based on a residual stiffness of the composite material, a second fatigue life value; respectively substituting property parameters of the composite material to be tested into the first fatigue life calculation formula and the second fatigue life calculation formula to obtain a first fatigue life value and a second fatigue life value; and comparing the first fatigue life value and the second fatigue life value, and outputting the smaller value of the two. The method and the system can predict the fatigue life of the composite material.
