Session 1 Introduction

Introduction: Any type of engineering system (Structural , Mechanical , Electrical , etc) is defined by: -Governing equation : coming from the fundamental principles of physics such as: equilibrium, conservation of energy, conservation of mass, and Newton's laws of motion -Boundary Conditions: that limits the behavior of the system and make it solvable (have unique solution). Example: Single spring problem is a very simple example of an engineering system.

Now imagine if the system was more complicated : -Non-simple arbitrary geometry. -Materials have complex behavior and properties. - Complex governing equation (Second-order Differential equations). -Even if we know the equation , no direct way of solving it !

-Divide the complex shape into lots of simpler shapes. (Discretization) -Solve the governing equation over each simpler shape. -Join all the simpler shapes together, ensuring compatibility and equilibrium at the inter-element boundaries. -But ! , This will require thousands of simultaneous equations.

-Equations are better represented in Matrix Format called : The Stiffness Matrix

-Solution Process is done using computer device. -Results often displayed on a contour diagram.

-Final Picture: Stress Distribution on the bridge

Finite Element Method Finite element analysis (FEA) is a computerized approximate method for predicting how an element reacts to real-world forces.

FEA works by breaking down a real object into a large number (thousands to hundreds of thousands) of finite elements, such as little cubes. Mathematical equations help predict the behavior of each element. A computer then adds up all the individual behaviors to predict the behavior of the actual object.
