A stable one-point quadrature rule for three-dimensional numerical manifold method

We present a numerically stable one-point quadrature rule for the stiffness matrix and mass matrix of the three-dimensional numerical manifold method (3D NMM). The rule simplifies the integration over irregularly shaped manifold elements and overcomes locking issues, and it does not cause spurious m...
