摘要: A detailed investigation of micro-scale damage development in uni-directional polymer composites under longitudinal loading (loading along the fiber-direction) has been presented current work. Three major modes have considered, namely, matrix damage, fiber-matrix interface debonding and multiple fiber fragmentation. The progression these their effect on overall stress-strain response reinforced plastic (UD-FRP) is interest. From study, it demonstrated that dimensions three dimensional repeating unit cell (3D-RUC) needed to generate repeatable results are inherently dependent volume fractions. length 3D-RUC longer for a higher In addition, physics fragmentation linked proximity other fibers triggering failure mechanics different from single behavior. Stochastic characteristics also studied by quantifying Weibull parameters micro-structure. (C) 2017 Elsevier Ltd. All rights reserved.
