Elasto-Dynamic Behaviour of Interacting Inhomogeneities and Cracks
The paper presents a theoretical treatment of the dynamic behavior of fibre reinforced composites containing matrix cracks and reinforcing inhomogeneities.A pseudo-incident wave method is used to treat the dynamic interaction between cracks and inhomogeneities.Using this method,the original interaction problem is reduced to the solution of coupled single crack/inhomogeneity subproblems,for which analytical solutions could be derived.The interaction effects are introduced via the superposition of the different subproblems.The steady state solution of the interacting crack problem is obtained using integral transform method and the solution of the inhomogeneity problem is determined using Fourier expansion.The dynamic stress intensity factors (SIFs) at the matrix crack are obtained and numerical examples are provided to show the effect of the frequency,geometry of microdefects and material properties upon the dynamic SIFs.
