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 …

Dynamic Stability of Uncertain Laminated Beams Subjected to Subtangential Loads
… of the inherent complexity of fiber-reinforced laminated composites, it can be challenging to manufacture composite structures according to their exact design specifications, resulting in unwanted material and geometric uncertainties. Thus the understanding of the effect of uncertainties in …

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 …

Forced vibration and hygrothermal analysis of composite laminated beams under the action of moving loads
… of simply supported glass/epoxy composite beams subjected to moving loads in a hygrothermal environment is carried out using the general purpose finite element program ANSYS. The moving load model and the hygrothermal incorporation are validated separately by reproducing results available …

Background for finite element analysis and experimental testing of glued-laminated space beams
Two straight and one curved Southern Pine glued-laminated beams are subjected to bending, bending and compression, and biaxial bending. The beams are tested at service loads and only one beam is loaded to failure. The analysis is performed by using the finite element program ABAQUS. The 3-D beam …

Nonlinear Analysis of Composite Beams under Random Excitations
… vibration responses of three unsymmetrically laminated beams, that are excited with a Gaussian random forcing function, are studied in this thesis. The beams are analyzed nonlinearly and compared to linear results, indicating some important corrections. The solution procedure begins with the …

Static and dynamic large deflection flexural response of graphite- epoxy beams
… flexural response and failure of graphite-epoxy laminated beams. The beam specimens were subjected to eccentric axial impact loads and to static eccentric axial loads, in order to assess the damage caused by impact. A geometrically and materially nonlinear analysis of the response and failure of …

Analysis of Static and Dynamic Deformations of Laminated Composite Structures by the Least-Squares Method
Composite structures, such as laminated beams, plates and shells, are widely used in the automotive, aerospace and marine industries due to their superior specific strength and tailor-able mechanical properties. Because of their use in a wide range of applications, and their commonplace in the …

Experimental investigation of a novel finite element model for Southern pine glulam beams
Glued-laminated wood (Glulam) is a versatile material manufactured by gluing two or more layers of wood together with the grain of all laminae running parallel to each other. Glulam beams of many sizes, shapes, and thicknesses can be made. Innovative load-carrying structures such as lattice domes, …

Integrated Sinc Method for Composite and Hybrid Structures
… methods for predicting interlaminar failure in laminated composites and hybrid material systems was examined. Because the Sinc methods first approximate the highest-order derivative in the governing equation, the in-plane derivatives of in-plane strain needed to obtain interlaminar stresses by …

The Next Generation of Residential Construction: Adoption of Green Building Programs, Environmentally Certified Wood Products and the Transparency of Environmental Friendliness
… LCA analysis was conducted for structural beams made from wood, steel, and concrete utilizing a “cradle-to-installed” methodology. Based on the results of the comparative analyses, wooden glue-laminated beams required 139% and 357% less primary energy during their manufacture than steel and …
