Asymptotic Analysis for the Eigenvalues of Peridynamic Operators

Abstract

Explicit representations of the eigenvalues of the peridynamic operator have been recently derived in [5]. These representations are given in terms of generalized hypergeometric functions. Asymptotic analysis of the hypergeometric functions is utilized to identify the asymptotic behavior of the eigenvalues. We show that the eigenvalues are bounded when the kernel is integrable and diverge when the kernel is singular. The bounds and decay rates are presented explicitly in terms of the spatial dimension, the integral kernel and the peridynamic horizon.
