A method, a system and a device for determining interlaminar shear strength of a composite laminated plate are provided. The method includes following steps: constructing a force-displacement curve of a composite laminated plate specimen based on strain data, corresponding to different displacements of the indenter, of the composite laminated plate specimen; determining a dominant strain based on plane strain nephograms; reading any defect in the plane strain nephogram corresponding to one displacement as a current defect, and determining a test force acting on the whole composite laminated plate specimen corresponding to the reference displacement of the indenter as a critical strain value; determining a product of the critical strain value and shear modulus under the dominant strain as the shear strength between adjacent single layers to be tested.
