In this paper, the energy absorption characteristics on extruded aluminum box-section strengthened with carbon-fiber-reinforced plastics (CFRP) laminates and/or foam material were investigated under impact loading. Impact tests using a pneumatic impact tester were conducted with the specimens in three-point bending flexure with consideration given to the side-door impact beams in vehicles. The absorbed energy to the specimen during the impact was determined from the loaddisplacement curve, which was obtained from the strain gauge attached to the impactor and the laser displacement transducer. From the results, it was found that the strengthening by externally bonding with CFRP laminates improved the impact-induced energy absorption. Also, the effect of the improvement was clearly seen in the case of the use of filling form material in the aluminum extrusion together with attaching CFRP laminates.

This paper investigates the impact-induced damage initiation and propagation in laminated composite shell under low-velocity impact. A three-dimensional eight-node nonconforming element with Taylor’s modification scheme is described to analyze interlaminar stress distribution and damage propagation. The damage analysis is performed by using the Tsai-Wu quadratic failure criterion, Tsai’s damage modes and an additional delamination formula at all Gauss points. The damage modes considered are matr...

In this paper, the geometric and material parameters of Graphite/Epoxy composite laminates such as span-to-thickness ratio, out-of-plane stiffness, orthotropy, stacking sequence are considered to investigate their influence on the mechanical behavior of composite plates under a low speed impact. Investigation is performed by means of two- and three-dimensional finite element methods combined with the modified Hertzian contact law, the failure criterion, and the degeneration of damaged elements. ...

Large deflection dynamic responses of laminated composite cylindrical shells under impact are analyzed by the geometrically nonlinear finite element method based on a generalized Sander’s shell theory with the first order transverse shear deformation and the von-Karman large deflection assumption. A modified indentation law with inelastic indentation is employed for the contact force. The nonlinear finite element equations of motion of shell and an impactor along with the contact laws are solved...

This paper gives details of the implementation of improved failure criteria for laminated composite structures into LS-DYNA3D. Out-of-plane stresses have been taken into consideration for damage initiation. It is suggested, for the first time, that delamination is constrained by through-thickness compression stress. Interactions between different damage mechanisms have been considered. Damage predictions in good agreement with experimental ones have been achieved.

This paper describes a procedure for the prediction of the threshold impact energy for the onset of delamination in fibre-reinforced quasi-isotropic laminates under low-velocity impact. It is primarily based upon two models. One is the energy-balance model which equates the kinetic energy of the impactor with the static deformation energy of the laminate. The geometrical non-linearity of the deformation of the laminate is also taken into account. Another model is the force-driven model previousl...

An investigation was performed to study the impact damage of graphite/epoxy laminated composites caused by a low-velocity foreign object. The impact damage in terms of matrix cracking and delaminations resulting from a point-nose impac tor was the primary concern. A model was developed for predicting the initiation of the damage and the extent of the final damage as a function of material properties, laminate configuration and the impactor's mass. The model consists of a stress analysis and a fa...

The impact response behavior of initially stressed composite laminates is investigated using the finite element method. An experimentally established contact law is incor porated into the finite element program. The Newmark time integration algorithm is used for solving the time dependent equations of the plate and the impactor. Numerical results, including the contact force history, deflection, and strain in the plate, are presented. Effects of impact velocity, initial stress, and the mass and ...

Abstract The understanding of the damage mechanisms for woven laminate plates under low-velocity impact is challenging as the damage mechanisms at the interface of adjacent layers are dominated by the fibre architecture. This work presents an experimental investigation of the behaviour of woven glass and carbon fibre composite laminates in a matrix of fire retardant resin under low-velocity impact. The performance is evaluated in terms of damage mechanisms and force time history curves. Six impa...

Low velocity impact tests at various energy levels were carried out on simply supported circular glass-fiber-reinforced plastic laminates made of glass fabric/epoxy prepreg. Four panel thicknesses, keeping the stacking sequence unchanged, and two tup diameters were employed, to verify the influence of these parameters on the elastic behavior and first failure conditions of the material. A four-parameter model considering the membrane effects and indentation, and explicitly accounting for the pan...

Low velocity impact and compression-after-impact characteristics of a typical plain weave E-glass/epoxy composite are studied experimentally. Atmospheric pressure was maintained on the top surface and different pressures were applied on the rear side during impact experiments. Pressure on the rear side of the impacted plate is referred to as back pressure in further discussion. Effect of back pressure on the impact behavior is studied. It is observed that the variation in peak contact force and ...
