Viscoelastic and Plastic Relaxation of Residual Stresses Around Macroparticle Reinforcements in Metal Matrixes

Equations are presented for the calculation of residual stresses generated by temperature changes in metal matrix composites. The interfacial contact pressures and plastic zone sizes for various cooling rates imposed on an Al2O3 sphere embedded in AA 355 Al alloy are evaluated. Stress relaxation and...

Zusammenfassung:Equations are presented for the calculation of residual stresses generated by temperature changes in metal matrix composites. The interfacial contact pressures and plastic zone sizes for various cooling rates imposed on an Al2O3 sphere embedded in AA 355 Al alloy are evaluated. Stress relaxation and alloy viscosity are important factors affecting the final residual stress state.--Chem. Abs.
