G. D. Ilyushin,L. N. Dem’yanetsthe boundary integral representation of the analogue of the single layer potential for elasticity. Because the stress discontinuities . and . are not in general physically meaningful the stress discontinuity method is an . method.faultfinder 发表于 2025-3-27 04:02:42
G. D. Ilyushin,L. N. Dem’yanetss are provided for both constant strength elements and straight line elements with piecewise linear approximations of the boundary parameters, and several examples are worked to demonstrate the accuracy of the approach. The chapter concludes with a discussion of curvilinear isoparametric elements wijungle 发表于 2025-3-27 06:06:25

Finally, a simplified Galerkin formulation of the displacement discontinuity method is provided to show how the system of algebraic equations can be written in terms of the displacement discontinuities at the element endpoints rather than at collocation pointoverhaul 发表于 2025-3-27 12:47:25
