For the finite element formulation a displacement field having five degrees of freedom is considered and a nine noded isoparametric element is used. The finite element model is developed using MATLAB code. The numerical results are obtained for the deflection of cylindrical shell for arbitrary boundary condition, stacking angle and radius to thickness ratio. The results are validated using literature and it shows good agreement

A DUCOM make pin on disc wear and friction monitor with the specimen as a pin with 12 mm diameter is used in the present experimental study. The specimen used in the present study is manufactured using vacuum assisted resin transfer molding technique for different lamination schemes. The results are obtained for different lamination scheme, track diameter, load and sliding distance. The results are obtained in the form of wear rate and coefficient of friction for different lamination schemes, loads and sliding distance. The results show that cross-ply laminates shows poor wear and friction characteristics than angle-ply laminates.

A seven degree of freedom and C 0 continuity finite element model using nine noded isoparametric elements is developed for precise computation of ply-by-ply stresses of laminated composite plate subjected to various bi-axial loading. The physically based Puck's failure criterion based on Mohr–Coulomb hypothesis and a degradation model proposed by Puck is used in the present failure analysis procedure for computing first-ply failure (FPF) and last-ply failure (LPF) stress. The finite element implementation is carried out through a finite element code developed in MATLAB, where material non-linearity due to material behaviour under in plane loading and post FPF damage, was taken into account. The results obtained by present approach are compared with classical Tsai–Wu, Tsai–Hill, Lee's failure criteria and experimental results available in various literatures. The FPF and LPF stress envelopes for a critical lamina are obtained for various lamination schemes, thickness ratio, modulus ratio and different biaxial loading conditions for symmetric angle-ply and cross-ply laminates.

System properties such as the material properties and lamina plate thickness are modeled as independent random variables.The mathematical formulation is based on higher order shear deformation theory (HSDT) with von-Karman nonlinear kinematics. An efficient C0 nonlinear finite element method based on direct iterative procedure in conjunction with a first order perturbation approach (FOPT) is extended successfully and applied for failure problem in random environment and is employed to evaluate the dimensionless mean failure load and variance of failure index by modeling the system properties as basic random variables using Tsai-Wu and Hoffman failure criteria.Typical numerical results are presented to examine the effect of amplitude ratios, boundary conditions, lamination schemes wi...

Stochastic finite element method (SFEM) based on higher order shear deformation theory (HSDT) with material non-linearity via second order perturbation technique (SOPT) is formulated for computing mean and coefficient of variation (COV) of FPF and LPF using Puck’s failure criteria. Failure strength of each ply and corresponding failure mode is predicted by using micromechanics based modeling approach. The effect of different environmental conditions, volume fiber fraction, lamination schemes, lamination angle, side to thickness ratio, different bi-axial loading on FPF and LPF response is investigated. The capability of the present SFEM in predicting FPF and LPF load statistics has been studied, by comparing the results obtained with the independent Monte Carlo simulation (MCS) technique. The predicted hygro-thermo-mechanical strengths of the several laminates are compared with the available experimental data and it shows good agreement.

This type of model is beneficial for determining the basic mechanical properties of a laminated composite with significantly lesser computational effort. In this work a formulation is presented which is based on Reddy's higher-order shear deformation plate theory which takes into account the effect of transverse shear deformation in composite laminates. This method is capable of finding equivalent homogenized properties for the laminated composite having any type of lamination scheme. Further this formulation is used to homogenized property of Grewia optiva fiber reinforced epoxy composite with different volume fraction and lamina scheme are calculated by using the proposed formulation. The accuracy and validity of the present computational algorithm is ensured by comparing the results with the available literature which provides good results.
