MATERIAL SELECTION AND FINITE ELEMET ANALYSIS SIMULATION
1. ABSTRACT The project involves the study and analysis of a billboard which have to fix under the condition of specific wind load. The analysis has required to finalize the product as well as to reduce the time involved in this. It is been give that the structure have to with stand the wind load with some required physical parameters. The project has to finalize by optimizing the structure so that it can be available for less cost. The design has been done by solid works 2011 software tool and the material is selected by CES selector 2005.
