On the method of virtual crack extensions
Web31 de dez. de 1997 · The virtual crack closure technique (VCCT) is a method used to extract Mode 1 and Mode 2 components of energy release rates from finite element fracture models. Energy release rate components extracted from an oscillatory delamination model using the VCCT are dependent on the virtual crack extension length, {Delta}.
