Simulations of nonlinear fracture process zone in cementitious material—a boundary element approach
A boundary element method based numerical model is presented to simulate the nonlinear fracture process zone in cementitious materials. A cohesive type stress-separation constitutive relationship (σ-w curve) is i...

On convergence rate of finite element eigenvalue analysis with mass lum** by nodal quadrature
Error bounds are obtained for the finite element eigenvalue analysis using the diagonal mass matrix lumped by nodal quadrature. Finite element results of various two-dimensional 2nd order eigenvalue problems a...
