Based on the elastodynamic responses of stress [[sigma].sub.ij] (i, j = 1, 2, 3) and displacement [u.sub.i] (i=1, 2, 3), which are obtained using the technique of explicit time integration in FE analysis of the cracked body, the dynamic J-integral (denoted as [J.sup.d]) is calculated as a post-processor by a volume integral, which is derived from a contour integral applying the divergence theorem, and the virtual crack extension method.

This paper studies the numerical contour integral methods (NCIMs) for solving free-boundary partial differential equations (PDEs) from American volatility options written on the volatility whose price follows four well-known models: GBMP, MRGP, MRSRP, and MRLP.
In this paper, we propose a novel and general method to study the local asymptotic stability of positive equilibrium of system (1) by the contour integral method.
