Zusammenfassung: | The invention discloses a method for determining an interface slip region of a metal-based composite material under a spectral load. The method comprises: step 1, solving stresses borne by a compositematerial matrix and fibers on a crack plane of a unit cell model based on the unit cell model with a matrix crack length; step 2, dispersing the matrix and fibers of the unit cell model with cracks in the step 1 into n units; step 3, establishing a friction slip model containing the crack length based on the step 1 and the step 2; and step 4, calculating the distribution rule of the interface slip region of the metal-based composite material under spectral load based on the friction slip model containing the crack length in the step 3. The method provided by the invention can effectively predict the distribution rule of the interface slip region of the SiC/Ti composite material under the spectral load.
