Resumen:
In the present paper a constitutive model adequate for the numerical analysis of the isothermal behaviour of a composite material is described. This approach is based on a generalization of the classical mixing theory by using a mixed formalism, which requires for an enhanced compatibility equation to describe the deformation field. Some details of a total Lagrange finite element formula-tion and two test examples to check for the validity of the model are also performed.
