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.
Each contour provides an evaluation of the contour integral. The number of possible evaluations is the number of such rings of elements.
