Abstract : The mathematical techniques necessary to evaluate the transient temperature distribution and histories in two-dimensional solids subject to a time varying radiant flux have been developed. In particular the finite difference form of the equations to be utilized in evaluating the thermal histories in solids of both rectangular and circular cross-sections are presented. The analyses allow for an arbitrary time dependent radiant flux to impinge upon the solids under investigation, and further assumes that the solids may exchange energy to space via convective and radiation processes. The solids are considered to be homogeneous, with temperature dependent thermal properties. (Author)
