simple bending theoryshear-lag analysisA one-dimensional analysis of a cross-ply laminate, containing cracked transverse plies, loaded in flexure is presented. Simple bending theory is used in conjunction with a shear-lag analysis, to calculate the degraded longitudinal modulus of a cracked transverse...
In the present work, a simple and refined trigonometric higher-order beam theory is developed for bending and vibration of functionally graded beams. The beauty of this theory is that, in addition to modeling the displacement field with only 3 unknowns as in Timoshenko beam theory, the thickness...

This method has also been used as a basis for the approximate dispersion and bending analysis presented in [56]. However, this reduced model cannot accurately predict modal properties such as dispersion, birefringence, or other polarization properties that depend critically on the spatial configuration...
whereb2is a bending modulus. By inserting the eigenvalue and associated eigenvector via Eq. (1) into the free energy contributions (Eqs. (2)–(4)), one can directly compareE-theory to existing models of smectics (Methods). When the lamellae phase is free of deformations, minimizing the ...
In this paper, a new simple higher-order shear deformation theory for bending and free vibration analysis of functionally graded (FG) plates is developed. The significant feature of this formulation is that, in addition to including a sinusoidal variation of transverse shear strains through the thic...

In particular pure mode II or dominantly mode II loading conditions cannot be introduced in practice using the vertical edge cracked long beam sample subjected to three-point bending. Although the problem of introducing full mode mixities in the beam specimen with higher aspect ratios can be ...
