Abstract:
In order to analyze beam structures more accurately and effectively, a two-node orthotropic beam element is proposed. This beam element is formulated using a consistent higher order deformation theory of orthotropic beams of which the transverse normal deformation can be effectively estimated. The stiffness matrix and the vector of equivalent nodal forces of the beam element are derived explicitly by the Galerkin method. In order to examine the reliability and the characteristics of the beam element, the analytical and the finite element solutions of a simple cantilevered beam are compared wit

Abstract:
Free vibration of two-directional functionally graded material (2-D FGM) beams is studied by the finite element method (FEM). The material properties are assumed to be graded in both the thickness and longitudinal directions by a power-law distribution. Equations of motion based on Timoshenko beam theory are derived from Hamilton's principle. A higher-order beam element using hierarchical functions to interpolate the displacements and rotation is formulated and employed in the analysis. In order to improve the efficiency of the element, the shear strain is constrained to constant. Validation o

Abstract:
Up to date, accurate prediction of interlaminar stresses is still a challenging issue for two-node beam elements. The postprocessing approaches by integrating the three-dimensional equilibrium equation have to be used to obtain improved transverse shear stresses, whereas the equilibrium approach requires the first-order derivatives of in-plane stresses. In-plane stresses within two-node beam element are constant, so the first-derivatives of in-plane stresses are close to zero. Thus, two-node beam elements encounter difficulties for accurate prediction of transverse shear stresses by the consti

A direct asymptotic integration of the full three-dimensional problem of elasticity is employed to derive a consistent governing equation for a beam with the rectangular cross section. The governing equation is consistent in the sense that it has the same long-wave low-frequency behaviour as the exact solution of the original three-dimensional problem. Performance of the new beam equation is illustrated by comparing its predictions against the results of direct finite-element computations.

Periodic structures play an important role in engineering since they allow the manipulation of the electromagnetic properties of certain materials. To design such structures and investigate their different properties, it is essential to use simulation techniques.

In this thesis, a three dimensional finite element method is used to obtain the band diagrams of periodic structures; hierarchal higher-order elements are employed, thereby opening up the possibility of goal oriented

Abstract:
Purpose – The rostrum of a paddlefish provides hydrodynamic stability during feeding process in addition to detect the food using receptors that are randomly distributed in the rostrum. The exterior tissue of the rostrum covers the cartilage that surrounds the bones forming interlocking star shaped bones. Design/methodology/approach – The aim of this work is to assess the mechanical behavior of four finite element models varying the type of formulation as follows: linear-reduced integration, linear-full integration, quadratic-reduced integration and quadratic-full integration.

Abstract:
This module, aimed at helping both English as a Foreign Language (EFL) teachers and their students, is the result of a qualitative, applied, transversal and constructivist research conducted with Open Lingua teachers. One of the objectives of said research was to establish the factors that favored and hindered the curriculum integration of open access bilingual dictionaries in that specific EFL context in order to design and implement some pedagogical and didactic initiatives that would foster the effective use of those lexical tools. The present module was a fundamental element within the ser

Abstract:
Laser beam welding (LBW) has become standard in many high-production and critical applications where the return on investment can be quickly realized due to the process' inherent efficiency in terms of weld penetration and travel speed. Also, some promising work has been done internationally related to the use of hybrid laser/arc welding (HLAW) for some applications (primarily shipbuilding), so this process variation was also included in the study. However, virtually all of the current LBW or HLAW applications are considered 'factory' applications, and therefore do not represent the logistical

DEVELOPMENT OF ANALYTICAL MODELS FOR PREDICTING THE FLEXURAL BEHAVIOUR OF ENGINEERED CEMENTITIOUS COMPOSITES – HIGH STRENGTH STEEL COMPOSITE BEAMS. The Hong Kong Institute of Steel Construction, 2023. http://dx.doi.org/10.18057/ijasc.2023.19.3.2.

Abstract:
This paper presents the results of three-dimensional (3D) finite element (FE) and analytical models on the prediction of the flexural behaviour of composite beams comprising high strength steel (HSS) I-section and Engineered Cementitious Composite (ECC) slab. In the FE approach, 108 composite beam models which cover a wide range of key parameters including HSS grade, ECC compressive strength, HSS section depth, ECC slab thickness, ECC slab width were generated and analysed. The flexural strength of these composite beam models was subsequently employed to validate the accuracies of some commonl

SECOND-ORDER ANALYSIS OF BEAM-COLUMNS BY MACHINE LEARNING-BASED STRUCTURAL ANALYSIS THROUGH PHYSICS-INFORMED NEURAL NETWORKS. The Hong Kong Institute of Steel Construction, 2023. http://dx.doi.org/10.18057/ijasc.2023.19.4.10.

Full text
Abstract:
The second-order analysis of slender steel members could be challenging, especially when large deflection is involved. This paper proposes a novel machine learning-based structural analysis (MLSA) method for second-order analysis of beam-columns, which could be a promising alternative to the prevailing solutions using over-simplified analytical equations or traditional finite-element-based methods. The effectiveness of the conventional machine learning method heavily depends on both the qualitative and the quantitative of the provided data. However, such data are typically scarce and expensive

STUDY OF MECHANICAL PROPERTIES OF A NOVEL COLUMN-BEAM-COLUMN PREFABRICATED STEEL FRAME JOINT. The Hong Kong Institute of Steel Construction, 2024. https://doi.org/10.18057/ijasc.2024.20.4.2.

Full text
Abstract:
Currently, most research on prefabricated steel frame joints focuses on column-column or beam-column connections. However, there has been a lack of effective research on prefabricated column-beam-column joints with higher construction efficiency. In this paper, we present the construction and installation process and technical characteristics of a novel prefabricated column-beam-column joint (NPJ). Initially, we describe the technical specifications of the NPJ. Following this, we examine the mechanical performance of the NPJ using a validated finite element model and conduct a detailed analysi
