Self-consistent thermo-viscoplastic constitutive model for short fiber composites Conference Paper

abstract

• The Benveniste reinterpretation of the elastic version of the Mori-Tanaka method is extended to model the viscoplasticity of composites containing voids and/or microcracks. The matrix unified viscoplasticity equations of Miller are cast in a total strain formulation to yield the instantaneous tangent stiffness for use in the micromechanics model. For steady state creep, the composite strain rate is given in terms of the matrix stress rate. Initial yield surfaces are drawn for SiC/Al composites.
