Deformation in Impacted Stitched Composite Plates Subjected to Compressive Load
The study on deformation in impact-damaged graphite-fibre/epoxy stitched composite plates subjected to compressive load is presented.A delaminated cross-ply laminate 03/903S obtained in low-velocity impact test has been examined using a self-designed anti-buckling device in compressive experiment.The out-of-plane displacement field of the specimen has been measured with an optical whole-filed measurement technique,which is carrier electronic speckle pattern interferometry (carrier-ESPI).Finite element (FE) simulation is also carried out to predict the deformation.The effect of the stitching line on compressive deformation is discussed for various stitched laminates.Finally,the numerical results are compared with experimental measurement deformations under different compressive loads.
