DAMAGE PROCESS AND ELASTOPLASTIC CONSTITUTIVE RELATIONS OF INTERFACE OF COMPOSITE MATERIALS

More Information
  • Received Date: May 29, 1998
  • Revised Date: September 05, 1998
  • The progressive interfacial debonding process and its influence on the elasto plastic stress strain relation of the particle reinforced composites under triaxial tension were studied. Weibulls theory of statistics is used here to express the damage process. Secant moduli are applied when the system is beyond the elastic limit. Numerical analysis shows that the damage procedures depend greatly upon the loading mode, strength of the interfaces and the shape of the particles.
