This paper presents a study of two-dimensional axisymmetric finite element analyses of a welded metal-reinforced thermoplastic pipe joint for stresses and deformations in order to understand the mechanical behavior. A stress redistribution phenomenon in the reinforcing skeleton is revealed. The results obtained from the destructive tests on butt couplings were compared with finite element models. Good correlations were found.
