主　　题：Composite damage blast load CFRP GFRP finite element analysis on LS-DYNA 

摘      要：The safety of civilian and military infrastructure is a concern due to an increase in explosive risks,which has led to a demand for high-strength civil infrastructure with improved energy absorption *** this study,a Finite Element(FE)numerical model was developed to determine the effect of hybrid Fibre Reinforced Polymer(FRP)as a strengthening material on full-scale Reinforced Concrete(RC)*** reinforcing materials under consideration were Carbon(CFRP)and Glass(GFRP)fibres,which were subjected to blast loads to determine the structural response.A laminated composite fabric material model was utilized to model the failure of composite,which facilitates the consideration of strain rate *** damaged area of the laminate is determined in the FE model,and it is in good agreement with the corresponding experimental results in the *** containing different stacking sequences were built to demonstrate their efficiency in resisting blast *** general,the damaged area was reduced when a hybrid reinforcement with CFRP as the top layer was used.
