| Abstract: | The mechanical characteristic of the expanded metal and its simplified analysis model, as well as its using in hydrolic engineering are proposed. A plate model is introduced to simulate the expanded metal, which is used in the experiment of covered way's liner, with equivalent in stiffness. With the finite element analysis method, calculation results using the plate model are close to those of experiments finished before. Accordingly, the simulation of plate model is doable and it also provides a simple and credible analysis method for expanded metal. |
