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…

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…

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…
