Abstract:

The CW laser irradiation code of Griffis, Masumura and Chang was modified to simulate pulsed laser irradiations. Extensive changes were required to cure the numerical instabilities produced in the code by the high peak powers common to pulsed lasers. The new code was tested against the original Griffis, Masumura and Chang code and against a simple heat capacity model. A comparison was made with some of the experimental pulsed irradiations of Cozzens, et al, resulting in doubts about the accuracy of the model for the thermal properties of the graphite-epoxy under rapid heating.
