Weakening of Elastic Solids by Doubly-Periodic Arrays of Cracks

  • W. R. Delameter

Problems concerning elastic bodies which contain multiple cracks are of obvious importance because the structural behavior of solids is strongly influenced by the presence of cracks. Solids containing cracks are weaker mechanically, not merely because at certain levels of applied loads the concentrated stresses at the crack tips may cause the crack to propagate and lead to fracture, but also because at lower stress levels the magnitudes of the elastic constants of the material can be significantly reduced by the presence of the cracks. Further, if the cracks are arranged in a preferred orientation, the elastic response of the body can be highly anisotropic.
