STUDY ON UNIAXIAL TENSILE PROGRESSIVE DAMAGE OF COMPOSITE LAMINATES WITH A HOLE
In response to the delamination phenomenon of composite materials
combined with a trilinear cohesive force model considering brittle fracture of materials
an Abaqus user subroutine was written using Fortran language to establish a three⁃dimensional progressive damage analysis model for composite laminates with a hole.Uniaxial tensile tests were conducted for four different layering methods
and modeling was conducted by using the commercial finite element analysis software Abaqus to analyze the hole edge damage of laminated plates.The results indicate that the proposed model can effectively predict the ultimate load and damage morphology of uniaxial tensile failure of composite laminates with a hole
and the failure zones of laminated plates are mainly concentrated at the hole edge.The research methods and results of this model can provide a reference for the design and maintenance of composite laminates.
