Finite element analysis of a laminated composite plate subjected to circularly distributed central impact loading

摘要: Abstract A two dimensional finite element analysis has been made for a fiber-reinforced composite laminate subjected to circularly distributed impact load which results, example, from impacting the plate with blunt-ended projectile. displacement model includes effects of transverse shear deformation and rotary inertia was used along Hamilton's principle derive matrices. Newmark's direct integration technique integrate respect time. The interaction force between projectile calculated by using Hertzian law contact. Results deformations are shown compare quantitatively experimental results. Numerical values stresses in were calculated.
