The elasticity modulus and mass density of the functionally graded beam are assumed to vary exponentially along its thickness direction. Local stiffness matrix model-based finite element analysis (FEA) is conducted to determine the bending stiffness and tensile stiffness of the section with a crack, ...
The protruded part is treated as a cantilever supported at its end by an equivalent spring group representing the part of fiber inside the matrix. The relationship between bridging stress and crack opening width is then calculated by the consideration of axial loading acting on the beam as well ...
In this study, a theoretical model incorporating an inclined pile group and a saturated half-space was established, wherein the pile and saturated soil were described by the E-B beam and Biot poroelasticity theories, respectively. The pile and soil were coupled through the receptance matrix, ...
The solution is stable if the real parts of all the eigenvalues of the matrix G are negative. So, having found the steady state solutions from the polynomials in Section 3, the stability of each solution is determined numerically from the eigenvalues of G (or its top left 4×4 sub-matrix...
The free field responses of the layered saturated poroelastic ground are obtained by the stiffness matrix method. The tunnel is assumed to be an infinitely long beam resting on a viscoelastic foundation. The soil skeleton displacements of the saturated ground are converted to dynamic loads imposed ...
