摘要
A continuum theory is presented for representing the high-temperature deformation behavior of metallic composite materials. The composite is considered pseudohomogeneous with its own properties that can be measured for the composite as a whole. A class of constitutive equations in which the inelastic strain rate and internal state are expressible as gradients of a dissipation potential function is extended for a composite. The potential is taken to depend on invariants that reflect local transverse isotropy. Applications illustrate the capability of the theory of representing the time-dependent, hereditary, anisotropic behavior typical of these materials at elevated temperature. © ASCE.
