Compression of thick laminated composite beams with initial impact-like damage
While the study of compression after impact of laminated composites has been under consideration for many years. the complexity of the damage initiated by low velocity impact has not lent itself to simple predictive models for compression strength. The damage modes due to non-penetrating. low …

Dynamic analysis and buckling of variable thickness laminated composite beams using conventional and advanced finite element formulations
The behavior of variable thickness laminated composite beams has not so far been fully understood. In the present thesis, a finite element formulation is established for uniform and variable thickness composite beams (externally and mid-plane tapered composite beams). First the conventional …

Thermal Bending, Buckling and Post-Buckling Analysis of Unsymmetrically Laminated Composite Beams with the Effects of Moisture and Geometric Imperfections
… buckling, and post-buckling of unsymmetrically laminated composite beams with imperfection under hygrothermal effects. Three different boundary conditions will be considered on this study. The non-linear governing partial differential equations are derived by taking into account the von-Karman …

A twenty DOF element for nonlinear analysis of unsymmetrically laminated beams
… analysis of symmetrically and unsymmetrically laminated composite beams including shear deformation. There is a need for a simple and efficient method for analyzing unsymmetrically laminated beams since no other study on this topic is currently available. The beam element has ten degrees of p …

Numerical Modeling and Analysis of Composite Beam Structures Subjected to Torsional Loading
… theoretical solution for the torsion problem of laminated composites. He adopted the traditional formulation of the torsion problem based on Saint Venant's torsion theory. The eigenfunction expansion method was employed to solve the formulated problem. The analytical method is proposed in this …

Nonlinear static and transient analysis of generally laminated beams
… and bend-twist couplings inherent to generally laminated composite beams. Further, a coupling between the shear deformation and the twisting is introduced. The lateral strains are assumed nonzero and retained in the formulation. The first model termed SVHSDT also accounts for the continuity of …
