Notations
εmu is the ultimate failure strain of the matrix.
We have not used 'f' as a suffix for failure to avoid confusion with 'f' for fibre.
σmu is the matrix failure stress.
σfmu is the stress in the fibre at the onset of matrix failure.
σmfu is the stress in the matrix when the fibres start to fracture.
