abstract
The explicit closed form fundamental solution of the elastostatic shallow circular cylindrical shell derived in Part I by Chen et al. [Int. J. Eng. Sci. to appear] is realized numerically. Major difficulties exist in approximating integrals of Hankel functions with irrational functions as arguments on the two-dimensional domain of definition. By analyzing the asymptotic characteristics of those integrals, we decompose the first quadrant of the (x, s)-plane into five regions, and apply appropriate exact, series-truncation, or quadrature algorithms on each region to compute numerical values of the three components of the fundamental solution. Comparisons of errors are tabulated and graphics of solutions are illustrated. 2000 Elsevier Science Ltd. All rights reserved.
