Insertion of Rotational Effects to the Calculation of J-Integrals Using Finite and Boundary Element Methods
Abstract
The calculation of J-integrals for cases with rotational effects using the finite orboundary elements needs special treatment. In this work, an attempt is made toderive the J-integral expressions for cases with rotational loading conditions. Newuseful ideas for reducing domain integrals to boundary integrals and improving theaccuracy of J-integrals are developed. The new ideas are implemented in finite andboundary element programs which were developed and validated in this work bytaking a case study of central-cracked rotating disc with known analytical solution.The results of the developed programs show good agreements with the analyticalsolution.
