摘要: Carbon fiber reinforced polymer (CFRP) composites possess inevitable geometric variabilities across scales, which directly relates to the fluctuations of mechanical properties. Meanwhile, complex damage and failure are involved in material behaviors. In this study, a phenomenological damage constitutive law of plain woven CFRP was first established based on experimental data. In order to further characterize the uncertainty of mechanical properties, a stochastic constitutive model was developed. A series of statistical volume …
