| Summary: | 碩士 === 國立臺灣大學 === 機械工程學系 === 85 === Thin film problems are very useful research topics in
engineering applications. The transient response of a thin film
subjected to moving loadings on the surface is analyzed in this
study. Two dimensional problems are usually discussed in two
cases. One is the so called anti-plane problem and the other is
the plane problem. We will investigate these two problems in
detail in this study.There are lots of investigations on the
transient response for which the applying dynamic loading are
all stationary. We will propose a methodology that can be used
to solve the transient wave propagation in a finite domain with
moving loadings. There are infinite number of waves will be
generated in the thin film system. It is convenient to use a
moving coordinate to solve the proposed problems in this study.
However, numerical results for both fixed and moving material
points are discussed.In constructing the solution, Laplace
transform and series expansion are used to solve the anti-plane
and plane problem. The full field transient solution in time
domain is constructed by using Cagniard-de Hoop method.
