A Study on Method and Modelling of Structural Analysis and Finite Elements: A Review
Abstract: The finite element method (FEM) or finite element analysis (FEA), is a numerical method usually employed for solving engineering (structural mechanics) and mathematical physics problems. Generally, the analytical solution of these problems require the solution to boundary value problems for partial differential equations. Specimens are usually tested and analysed using finite element method (FEM) for investigating the behaviour of square concrete columns confined by fibre reinforced polymer (FRP) and sheets.

Assumptions, Limitations and Applications of Bernoulli’s Equation
Abstract: The Euler-Bernoulli beam theory, also called “beam theory”, is a condensed version of the linearisotropic theory of elasticity and can be used to predict the load-carrying and deflection properties ofbeams. It was initially stated around the year 1750, but it was not widely used until the Eiffel Towerand the Ferris Wheel were built in the late 19th century. It immediately became an engineering pillarand a catalyst for the Second Industrial …
