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 stresses POLYMER-MATRIX COMPOSITES INTERPHASE COMPUTATIONAL SIMULATION Anifantis, N.K. https://drive.google.com/file/d/18iQa--6KVzIqYrx8Tx20DfVgZkeyBkKd/view?usp=drivesdk Para ver el documento ingresa a Google con tu cuenta: @cicy.edu.mx Loc REF1 250602s9999 xx |||||s2 |||| ||und|d 24590 24590 0 0 Loc 0 0 F1 CICY CICY RE 2025-06-25 0 B-14463 2025-06-25 15:39:42 2025-06-25 REF1
