Equation of State Properties of Modern Composite Materials: Modeling Shock, Release and Spallation

摘要: As Finite‐Element codes with explicit time integration schemes (Hydrocodes) are intensively used to simulate fiber reinforced composite structures under impact loading, reliable material models thoroughly derived parameters essential for successful simulations. The paper describes a closed approach derive and validate the Hugoniot curve, release properties (Gruneisen Γ) spall strength using combined experimental numerical methodology. method is applicable wide range of materials, exemplary results shown high Carbon‐fiber / Epoxy laminate (CFRP) in aeronautic low stiffness, highly deformable Aramid protection material.
