Tensile Cohesive Laws of Adhesive Joints as a Function of the Adhesive Thickness

Because bonded structures bear such a high level of responsibility, it is critical to accurately predict fracture behaviour under a variety of stresses. Numerical simulations, similar to Cohesive Zone Models (CZM), can be used for strength prediction. The influence of adhesive thickness (tA) variation on the value of tensile fracture toughness (Gnc) of a bonded […]

Advanced Numerical Techniques for Strength Prediction of Adhesive Joints under Peel Loadings

Adhesive bonding is becoming more popular for structural applications due to benefits such as more uniform stress distributions and the ease with which diverse materials may be joined. There are many different types of joint architectures, but the most prevalent are single-lap joints (SLJ), double-lap joints, and scarf joints. T-joints are used in aeroplanes to […]

Analysis of Torsional Tubular Adhesive Joints using a Numerical Finite Element Approach

Tubular bonded joints are frequently exposed to axial or torsional stresses. The weight reduction of the structure and ease of manufacturing are two advantages of this form of connecting over additional welding or mechanical joining. The torsional performance of three adhesives in aluminium tubular joints (AW6082-T651) is compared in this study, which takes into consideration […]

Insight on the use of Cohesive Zone Models for Impact Strength Analysis of Adhesive Joints

Adhesive bonding are becoming more popular as a substitute for technical applications. The growing popularity of this sort of joining necessitates the development of tools to aid in the design process. Cohesive zone models (CZM), which combine strength and toughness characteristics to forecast the performance of adhesive joints, are one of the most effective damage […]

Evaluation of Adhesively-bonded Stiffeners by Numerical Modelling

In every sector, large-scale application of a certain bonding method need precise instruments for failure design and prediction. This study looks at how well a structural adhesive (AralditeĀ® 2015) performs on a T-stiffener with composite adherends comprised of an epoxy matrix reinforced with carbon fibres. The goal of this research is to use the Finite […]

Evaluation of Bonded Joints by Cohesive Zone Models: A Descriptive Study

Cohesive Zone Models (CZM) are commonly used to forecast adhesive junction strength. This research investigates the impact of various analytical conditions, especially cohesive parameters, utilised in CZM simulations to represent a thin adhesive layer in single-lap joints (SLJ) under tensile stress, on strength prediction under various geometrical and material circumstances. The researchers looked several adhesives […]

Comparison of Uplift Pressure and Hydraulic Gradient in Three Types of Dams: Concrete Gravity Dams, Homogeneous and Heterogeneous Earth-Filled Dams

Dams are among the oldest hydro-engineering structures on the planet. They’re built to prevent flooding and protect land, property, people, and cattle. Dam designers must understand uplift pressure and hydraulic gradient since they have an impact on the dam’s stability. Dam stability relates to the dam’s ability to withstand sliding, overturning, and maximum stresses (tension […]

Parametric Analysis and Photo Elastic Experiment of Stress Concentration Factor and Its Mitigation in Rectangular Plate with Opposite V- notches Subjected to In-Plane Loading

Various studies look at flat plates with sharp V-notches that are subjected to axial loads. There have been few attempts to reduce the stress concentration factor caused by V-notches. The current study uses an area reduction method to mitigate the stress distribution caused by a V notch under in-plane static loading in rectangular isotropic plates. […]

Finite-element Modeling for Analysis of Isotropic and Orthotropic Beams Using First Order Shear Deformation Theory

A finite element model is built in this paper to analyse the response of isotropic and orthotropic beams, which are common structural elements in aeronautics and astronautics. A first order shear deformation theory, the Timoshenko beam theory, is used to represent the supposed field displacement equations of the beams. Hamilton’s theorem is used to derive […]
