Using the constructed three-dimensional progressive damage degradation model for composite based on the theory of continuum damage mechanics(CDM),dynamic response and damage performance of composite laminate under the act of lightning strike impact force were analyzed through the platform of ABAQUS software and VUMAT subroutine.Analysis results indicate that under the act of lightning strike impact force,laminate displays oscillatory movement with amplitude decrease,and the work did by lightning strike impact force converts with internal energy and kinetic energy of laminate mutually,and accompanys with the consumed viscous dissipation energy,additionally,it can be expressed as a function of electrical charge and action integral of lightning current.Mechanical impact damage degree of laminate depends on the work due to lightning strike impact force,for the same material,matrix,fiber and delamination damage exist different corresponding critical damage external energy,respectively.When the work did by lightning strike impact force higher than the critical damage energy,laminate will occur corresponding damage form.With the same boundary support condition,the maximum value of fiber,matrix and delamination damage state variables depend on total work did by lightning strike impact force,and have nothing to do with lightning current parameters.
