It has been observed that static-load second-order response surface method gives certain accuracy in finite element model updating for bridges. School of Water Conservancy & Environment Engineering, Zhengzhou University, Zhengzhou 450002, China;2.

The governing equations, which account for the coupling between various physical phenomena, are derived within the framework of the generalized Biot theory.

Computer simulations have become a useful part of mathematical modeling of many natural systems in physics, astrophysics, chemistry and biology, human systems in economics, psychology, social science, and engineering.

Simulation of a system is represented as the running of the system's model.

It is illustrated that incorporating the coupled physical processes, i.e. In this paper, the bending and the free flexural vibration behaviour of sandwich functionally graded material (FGM) plates are investigated using QUAD-8 shear flexible element developed based on higher order structural theory.

the solid skeleton deformation, the fluid flow in the fracture and in the pore spaces of the surrounding porous medium and the hydraulic fracture propagation, is crucial to provide a correct solution for the problem of the fluid-driven fracture in porous media, where the poroelastic effects are significant. This theory accounts for the realistic variation of the displacements through the thickness.
