Advances in composite laminate theories

The results indicated that the HFGMC shows a higher accuracy than the GMC for perfecting the transverse response of composites with imperfect interface bonding. The micro-strain field can be extracted at every node or integration point within the representative volume element.

Penetration of Semi-Infinite GFRP Laminates The types of projectiles life bullets that were used are the rigid projectile with ogival and conical nosed. The free and forced vibration response of laminated composite folded plate structures was predicted by a nine-node Lagrangian plate-bending finite element with five engineering DOF per node that incorporated rotary inertia.

However, there exist material and thickness discontinuities between the unreinforced and reinforced regions of the plate. Once the state equation for the out-of-plane variables is obtained, a complex boundary value problem is converted into an equivalent simple initial value problem.

In both pre-buckling and buckling analyses, the form of the assumed functions real or complex does not necessarily satisfy the kinematic boundary conditions. The results showed that the theoretical prediction exhibits good agreement with experimental results only when both imperfect interface bonding between fibers and matrix and thermal residual stresses in subcells are taken into consideration.

The strategies for forecasting strength or deformation at failure point for composites are therefore highly diverse as are the related models Chamis, Stiffness and expansion estimates for oriented short fiber composites [Revue]. A finite element model is developed by Liu et al.

Therefore, it is necessary to develop appropriate models capable of accurately predicting their dynamic characteristics. Under these conditions, Equation 14 gives relationship between the lamina stresses and strains referenced to the principal material axis i,2.

Furthermore, an experimental determination of the first failures is very delicate to achieve. A finite element model, based on third-order shear deformation theory, is used in this study by Latheswary et al.

Regarding resins with large deformations, an extension of the mixing law means that resistance along the X fibre direction can be predicted Tsai, REV homogenization techniques are currently finding a second wind thanks to the work done by Ha Ha and Huang, These models do not take into account the influence of the thickness of the plies or the presence of adjacent folds.

Furthermore, in many cases, the characterization tests will only yield some of a material's characteristics. Also, new numerical results are presented and some results are compared with existing values in the literature.

Cambridge university press, The macroscopic strain state in each lamina is determined using the process described in Section 5. By employing the higher-order displacement expansion, the high-fidelity generalized method of cells HFGMC was proposed for solving microscopic stress-strain field with a higher accuracy [ 1011 ].

For the finite element method, poor calculation efficiency, difficult modifying for the structure model, results in a poor application in studying microstructure variation effects on the macroscopic mechanical responses.
