Course objectives

To explain the basics of atomic bonding, crystal
structure, materials imperfections, and the
different materials classes.
To explain the mechanical and thermal materials
properties and their relationship to the
microstructure as well as the environmental
effect on the material properties.
To introduce the concept of materials selection
for a certain application.
To introduce the basics of biomaterials,
biocompatibility, and bioreactor structure
materials.

6
Learning outcomes

After studying this course, the students would be
able to
Identify the material microstructure needed to
obtain certain properties.
Determine the mechanical properties associated
with elastic, plastic, and viscoelastic material
behavior.
Select a certain material for a specific
application using material selection charts and
performance indices.
Identify suitable materials to be used as
biomaterial or bioreactor structure materials
based on the operating conditions.

7
Dress code in attending classes

Matric card must always be displayed.
No round neck shirt.
No slippers.
No tight pants or shirt.
No long hair for brothers (cap should be removed
while in the classroom)

INTRODUCTION

Materials to the engineer are like the human body
to the physician a manifestation of Allah
creation

14
Material science VS. Human behavior

Elastic-Plastic limit, yield point, permanent
deformation, maximum stress, failure stress.
Ductile vs. brittle fracture.
Strain hardening.
Plastic deformation by dislocation motion

15
Material engineering VS. Bioengineering

In the beginning, material application was a
problem of material choice.
These days, scientists can device their own
materials !
In material engineering, no ethical problems
(compared with bioengineering).

16
Engineering materials WHY

Materials is the queen technology of any advanced
technical system. The economics eventually
depend on the materials, the reliability depends
upon the materials and safety depends upon the
materials

17
Materials are not just input !

Modern thermal power stations (e.g., boiler
liners).
Electronic industry (e.g., semiconductors)
Nuclear reactors (e.g., reactor core)
Space shuttles (e.g., shuttle surface tiles)
Weapons (e.g., Shells and armors)

Biomaterials WHY

Tissue Engineering
Each year in the US, organ and tissue loss
accounts for an estimated US400 billion.
Patients waiting for organ transplantation rose
from about 27,000 in 1988 to 65,000 more in 1995.
New Straight Times, 6/11/2002
Four core technologies for tissue engineering
Biomaterial technology, cell technology,
construct technology, bioreactive technology for
the organ and tissue generation.

27
Biomaterials, Global Market Scenario

1996 USD4.3 billion world-wide
2004 USD7 billion USA alone

Biomaterials, Malaysian Market Scenario

1995 Imported USD6 million - Orthopaedics
Dental products
Presently Produced - Latex-based products
simple medical devices

28
Please, dont forget !

There is a need to develop a sense of feeling for
numbers, properties, materials,
Look carefully at tables, figures.
Compare and understand different figures.
Pay attention to Summary part of each chapter.
Use the CD supplied with the text.
