The solutions are determined by superposition of the fundamental solution in the Laplace transform domain. The fundamental solution is the exponentially distributed traction on crack faces. The exact close form transient solutions of dynamic stress intensity factor are expressed explicitly in time domain. These solutions are valid for an infinite length of time and have accounted for the contributions coming from incident, reflected and diffracted waves. Numerical results of dynamic stress intensity factors are obtained and compared with the corresponding static values. The transient solution is shown to approach the static value after the first few waves interactive with the crack tip have passed. © ASCE.application/pdf777213 bytesapplication/pdfen-USCracks; Dynamic Analysis; Laplace Transformations; Stress Wavesjournal article2-s2.0-0028333194http://ntur.lib.ntu.edu.tw/bitstream/246246/86374/1/33.pdf
