• INTRODUCTION
• Most of the classroom teaching is conducted using
  transparency and PowerPoint presentation to
  deliver the lecture material.

5

• INTRODUCTION
• For instance, the stresses, strains and
  deformations of an object are the important
  parameters to illustrate the structural behaviour
  subject to loading.

• However, these phenomenon are too abstract to
  show using transparency and PowerPoint
  presentation.

6

• PROJECT OBJECTIVE
• The primary objective of this project is to
  develop 3D visualization and simulation of
  structures using finite element analysis to
  enhance student understanding.

• In the 3D computer animation, the stresses,
  strains and deformations of a structure are
  clearly shown.

• Different stress levels are shown in different
  colour, and the deformations can be physically
  seen in the animations.

• The 3D computer animation can be uploaded to the
  web for adoption in other engineering courses.

• Conclusions
• The 3D visualization and simulation is a useful
  tool for teaching.

• The stresses, strains and deformations of an
  object can be shown using the 3D visualization
  and simulation method. These parameters are
  important to illustrate the structural behaviour
  in engineering concepts.

• Different stress levels can be shown in different
  colour. The deformations can be physically seen
  in the animations.

• The money obtained from CELT is very useful for
  teaching in UST.
