ABSTRACT

The goal of the research is to develop Geogrid special-purpose design systems that are the scientific and effective methods to substitute the traditional manual computation and reduce the error. The manual computing methods cannot predict that the product is whether qualified before experiments or tests .The developed design systems will offer engineers cored design date before the products entering markets. This article uses UIDL in ANSYS, which is the analysis commercial software of Finite Element Method, to establish Geogrid design systems that provides an easy-to-use environment for user and has been trusted to deliver accurate results quickly. In Geogrid special-purpose design systems by UIDL, the users only need to operate simply to complete analysis with GUI. The product can conform truly the quality to design. Besides, the personnel training time is reduced in Geogrid design system with GUI.

Keywords : Geogrid ; FEM ; UIDL ; ANSYS
