Учет анизатропии свойств в модели межслойного разрушения при сверлении композиционных материалов

Abstract

The problem of crack delamination appearance and propagation in the drilling of composite laminates with account of anyzatropic properties of material is considered. This model for local fracture using a linear fracture mechanic, and coupling with known empirical dependences used for rational choice of parameters for drilling epoxy carbon-filled plastic. The take account of anyzatropic properties is more strong limitation of feed rate choice than for using isotropic model.
