20.2.2. Finite Element Method (FEM)

Try these first

1. 1.

   What is FEM?

   Hint

   Think about how large problems can be simplified.

2. 2.

   Name one application of FEM.

   Hint

   Consider fields that involve complex geometries.

3. 3.

   What does FEM stand for?

   • Finite Element Method
   • Fast Element Method
   • Finite Energy Method

   Hint

   It's a method used in numerical analysis.

4. 4.

   True or False: FEM is primarily used for problems with simple geometries.

   • True
   • False

   Hint

   Consider where you might need to break down geometry.

5. 5.

   You are tasked with designing a new bridge using FEM. Outline the steps you would take from the initial design to final analysis.

   Hint

   Think step-by-step, as each part of the process builds on the previous ones.

6. 6.

   Critique the following statement: 'FEM is only useful for linear problems.' Discuss how it applies to nonlinear cases.

   Hint

   Recall examples where materials behave differently under certain stresses.
