    Abstract
  • A 3D progressive damage model and finite element method were used to analyze the impact properties and mechanical properties of composite case after impact under static loading.The matrix-cracking,matrix-crashing,delamination,and fiber breakage may occur in the case after impact.When the impact energy exceeds 26 J,the impact damage can spread rapidly under the given static loading.
