The formulation of a generalized computational simulation developed to treat speci®c features of these materials yields stress predictions using a ®nite- element approximation. The parametric description of the geometry and the incorporation of material inhomogeneities by a sequence of homogeneous subregions allows for the treatment of any material combination including closely packed composites and conditions of imperfect adhesion. Considering square and hexagonal arrays of ®bers, two major ®nite-element grids were generated where the features and the constrains are automatically being assigned. Numerical results illustrate the in¯uence of material parameters on local critical stress states and indicate regions of high stress concentration. It has been proved that, ®ber interaction substantially intensi®es stress concentrations within the interphase region, although imperfect adhesion relieves stresses14aPOLYMER-MATRIX COMPOSITES14aINTERPHASE14aCOMPUTATIONAL SIMULATION12aAnifantis, N.K. 40uhttps://drive.google.com/file/d/18iQa--6KVzIqYrx8Tx20DfVgZkeyBkKd/view?usp=drivesdkzPara ver el documento ingresa a Google con tu cuenta: @cicy.edu.mx  2LoccREF1250602s9999    xx |||||s2   |||| ||und|d  c24590d24590  00102Loc40708F1aCICYbCICYcREd2025-06-25l0oB-14463r2025-06-25 15:39:42w2025-06-25yREF1
