SCOPE OF THE PRESENTATION

• INTRODUCTION
• FINITE ELEMENT ANALYSIS FOR RESEARCH
• FINITE ELEMENT ANALYSIS FOR TEACHING
• CONCLUSIONS

However, these kinds of presentation are constrained in 2D. For most engineering concepts, it is necessary to show the object in 3D.

INTRODUCTION

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

SCOPE OF THE PRESENTATION

• INTRODUCTION
• FINITE ELEMENT ANALYSIS FOR RESEARCH
• FINITE ELEMENT ANALYSIS FOR TEACHING
• CONCLUSIONS

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.

Conclusions

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