Numerical method for failure simulation of unidirectional fiber-reinforced composites with spring element model

Stress redistribution around clusters of broken fibres in a composite

“…(1) can be particularly useful for models predicting the strength of fibre bundles. While some fibre bundle models [22] take into account the dependency of l e with n b , others [40,41] assume that the recovery length is insensitive to the size of the broken 210 cluster. The results in Fig.…”

“…Models can also be based on a hierarchical build-up of the failure process [22]; this approach is computationally very efficient and the predictions were found to compare favourably with 40 experimental results on several composites in the literature.…”

Synchrotron radiation computed tomography for experimental validation of a tensile strength model for unidirectional fibre-reinforced composites

“…The methodology is based on the works of Curtin, Okabe and co-workers [11,18,[47][48][49]. After assigning a…”

“…Many theories exist to predict the tensile strength of UD composites [11][12][13][14][15][16][17][18][19][20][21][22][23], and most of these contain three key features. The first is the assumption of a Weibull distribution of fibre strength, which is determined by the random distribution of flaws in the fibre [23].…”

Modelling hybrid effects on the stiffness of aligned discontinuous composites with hybrid fibre-types

“…Moreover, the matrix thickness t m defined in Equation 27 is the same for all interactions in a given composite, and is assumed to be uniform along the perimeter of the fibre, as done in most models in literature [18][19][20].…”
