A thermoelastic model for the calculation of stresses induced during the in-situ consolidation process for thermoplastic composites is developed. The model is composed of two infinitely long layers of orthotropic material moving at a constant velocity through a concentrated heat source. The two layers are continuously joined along the semi-infinite surface downstream of the consolidation point. The model is developed in three stages, consisting first of a thermoelastic particular solution and an isothermal complementary solution for each layer and finally a solution of the mixed boundary value problem defined by the contact between the two layers. The sum of the particular and complementary solutions satisfies the equilibrium and prescribed boundary conditions for each layer. The conditions of partial contact between the layers result in the existence of unknown tractions along the contact surface. An approximate numerical procedure for the solution of these tractions is outlined. Numerical examples are given that illustrate the results for a two-layer thermoelastic static contact case and for a two-layer quasi-static case simulating the thermal and transport effects of a laserassisted in-situ consolidation process. |
