| Summary: | 碩士 === 國立臺灣科技大學 === 營建工程技術學系 === 82 === The purpose of this work is to obtain the analytic solution and
the dynamic J-integral of two-dimensional elastic body
containing a mode-I crack propagating with a supersonic
velocity by a mathematical model and numerical calculations.
The method used in the study is the method of self-similar
potentials (SSP) in conjunction with the Gauss quadrature. The
method of self-similar potentials is used to analyze the two-
dimensional problem of mode-I crack propagation, while the
Gauss quadrature is for numerical calculation. After we solve
this problem, emphasis will be placed on the displacement and
stress behaviors near the crack tip and phenomena of wave
propagation, and finally the value of J-integral for dynamic
crack problem is evaluated.
