Computer is applied in different fields of mechanical engineering such as design, manufacturing, thermo-fluids, experimental data modeling & simulation , smart administration . The derived formulae of some fields such as material strength- heat transfer- fluid- vibrations are differential equations or partial differential equations. It is difficult to solve differential equation for complicated bodies or systems with various properties. Finite Elements is a numerical method developed to solve complicated differential equation. Its idea is dividing the body or the system into finite number of simple units called elements and then solving the equation for each element numerically. The overall numerical equation is the summation of individual numerical equations of the elements, usually in Matrix form. The overall equation is solved after applying the boundary conditions
OBJECTIVE
In this course, only finite element for structural (strength of materials) is studied. The purpose of this analysis is to study the stresses and strains in the critical area in the body or the system so as to avoid failure. The objective of the course is to enable the students to be acquainted with:
1. The general application of computer in mechanical engineering and the related software
2. Finite element method for
a) 1D (springs, bars, trusses and beams)
b) 2D plates
c) 3D bodies
3. Solving finite element problems using MATLAB
