Buckling of fibres embedded in a matrix analysed with the Discrete Element Method

In this research, the influence of physical properties on the buckling stability of fibres embedded in a matrix is studied using a linear and non-linear Discrete Element Method (DEM). A MATLAB model is created to analyse the influence of non-linear matrix behaviour to the buckling behaviour of individual embedded fibres. The model is extended towards fibre bundles and the influence of initial fibre imperfections and the fibre volume fraction is studied. An overview of parameters influencing the buckling behaviour of fibres in unidirectional fibre reinforced composites is presented.
