摘要：

This paper describes an investigation into the error bounds of Gauss-Legendre integration for non-singular integrals in three-dimensional boundary element analyses. Based on these numerical results, reliable and efficient criteria for adaptive integration routines are proposed. Because these criteria are in simple forms, they can be implemented within boundary element algorithms without difficulty. Numerical examples have been presented to demonstrate the efficiency and accuracy of the proposed integration schemes.
