Calculation of Stretch Stress of Double-Layer Plate Composites

Article Preview

Abstract:

The stretch stress of each layer of laminate composite undergoes complex changes after being stretched, which significantly affects the stretch strength. In order to determine the magnitude of the change, the paper directly solved the stretch stress using the analytical method through simple assumptions, and obtained the analytical calculation formula. Studies on double-layer plates show that the magnitude of stretch stress is closely related to the elastic modulus, length and thickness dimensions of the plate layer, the shear modulus of the adhesive, the thickness of the adhesive layer, and the external stress, and the maximum stress occurs at the middle section. The calculation of the formula provides a convenient way to check the stretch strength.
