Abstract
A molecular dynamics simulation of mode I crack propagation is carried out. We propose a definition of the J integral in terms of atomistic information, i.e. site potential energy, atomic stress, gradient of displacement and so on, and call it Ja parameter. The crack tip opening displacement, the crack extension, stress distribution and number density are evaluated in the vicinity of the crack tip. The relationship between the crack growth and Ja parameter is discussed.
