Abstract

In this paper a problem of debonding of fibers from matrix, the influence of loading choice, prevailingly in normal direction, and a range of damage after finishing the disconnection of both phases are studied. The generalized Mohr-Coulomb interfacial condition is taken into account and the tensile stresses at the fiber-matrix interface are excluded. The loading is introduced in the classical way in the sense of Suquet and moreover, the influence of eigenstrain or eigenstress is considered. The results are mutually compared, considering partial loadings, and evaluated in such a way that the properties of homogenized composite structure should be determined in the final stage of computations, it means the overall behavior of the composite aggregate should be described from the results of this paper. Using the general Suquet idea applied to loading of
