Nonlinear dynamic response for composite laminated beam with delamination under considering the effect of contact

It is significant to study the numerical simulation method of the flexural failure process of laminated beams reinforced with woven fabric.

In this paper,bending failure experiments have been carried out for five groups of laminated beams reinforced with unidirectional woven fabrics.

Analysis on contact damage problem of composite beam;

The nonlinear contact problem of composite beams is linearized by an inverse method, that is to say, the loading distribution on the contact zone with the adjustable parameter and the contact width are assumed to be given and the curvature of the cylinder is to be solved.

The vibration of a composite beam, embedded with piezo-electric film, is analysed in the paper, Hamilton principle is made in use to analyse the coupled effect between piezo-elec-tricity and structure deformation,considering the influence of electric field on deformation, the e-quation of motion of a composite beam is derived.

An analysis of tension and bend coupling effect for laminate beam;

A composite laminate beam element based on the higher-order shear deformation theory;

For the delamination of composite laminate beam stacked orthogonally and symmetrically with four plies under transverse loading, the magnitudes of J1 -integral along different paths are obtained on the basis of the determination of the SIF and all of the coefficients in the expansions.
