ELASTOPLASTIC ANALYSIS OF LAYERED METAL-MATRIX COMPOSITE CYLINDERS .2. NUMERICAL RESULTS

Part I (Salzar et al, 1996) of the paper presented an exact elastic-pl astic analytical solution for an arbitrarily laminated metal matrix co mposite tube subjected to axisymmetric thermo-mechanical and torsional loading. In Part II, this solution strategy is first validated by com parison with available closed-form solutions, as well as with results obtained using the finite-element approach. Subsequently, examples are presented that illustrate the utility of the developed solution metho dology in predicting the elastic-plastic response of arbitrarily layer ed metal matrix composite tubes. In particular, optimization of the th e response of composite tubes under internal pressure is considered th rough the use of functionally graded architectures.
