| Summary: | 碩士 === 國立海洋大學 === 造船工程學系 === 83 === In this paper, a complete computer aided engineering
system for the stress analysis of notched structure is
presented. In which, the selection manufacturing and
stress measurement of the specimen and the numerical
analysis is all included. At first, finite element
analysis is made for the determination of the
geometry and loading of the specimen. After that, the
specimen are manufactured by CNC machine and tension
testing are performed by using unversal test machine. The
testing results are compared with those from finite
element analysis. Furthermore, by reducing the radius of
notch step by step, stress intensity factor（SIF）of the
corresponding cracked structure are derived successfully
from a special series form of stress concentration factor（SCF
）.
