Advanced Mechanics of Materials


材料力學進階
(EM3)

Fall, 2000


Ins tructor:
劉昭華


(Room: E785)


Course Objective:


The objective of this course is to introduce solutions of simple structures

made

of

line
ar
elastic, viscoelastic, and composite materials. In order to do this general stress
-
strain
relations are studied first, then stress analysis techniques are discussed. The concepts of
yielding and plastic flow, as well as the mechanics of fracture and f
atigue are also included in
this course because they become more and more important in mechanical design. A
special
fe
a
ture

of this course is that material

s mechanical properties, such as atomistic view
of elasticity, dislocation theory of yielding, and
a
tomistic
fracture m
odels
,

are briefly
discussed.
