A micromechanics approach for damage modeling of polymer matrix composites
نویسندگان
چکیده
A new model for damage evolution in polymer matrix composites is presented. The model is based on a combination of two constituent-level models an9 an interphase model. This approach reduces the number of empirical parameters ·since the two constituent level models are formulated for isotropic materials, namely fiber and matrix. Decomposition of the state variables down to the micro-scale is accomplished by micromechanics. Phenomenological danlage evolution models are then postulated for each constituent. Determination ofnlaterial parameters is made from available experimental data. The required ·experimental data can be obtained with standard tests. Comparison between model predictions and additional experimental data is presented.

متن کاملFinite element modeling of polymer matrix nano-composites reinforced by nano-cylindrical fillers
A new three-dimensional unit cell model has been developed for modeling three constituent phases including inclusion, interphase and matrix. The total elastic modulus of nano-composite is evaluated. Numerical results are in good agreement with the previous proposed theoretical modeling. Higher matrix and inclusion elastic modulus both can dramatically influence the total elastic modulus.
