Fatigue crack growth in thin notched woven glass composites under tensile loading. Part II: modelling [PDF]
, 2011 Fatigue propagation of a through-the-thickness crack in thin woven glass laminates is difficult to model when using homogeneous material assumption. Crack growth depends on both the fatigue behaviour of the fibres and of the matrix, these two phenomena ...
