Abstract
A grid structures are the shell like structures such as orthogrid, isogrid which supports the skin of any structure. When made up with composite materials Grid structures find very good application in aerospace field. The properties of the skin can be uniformly distributed, thickness of the skin can be reduced which intern reduces the total weight of the structure. For the present skin stiffened structures orthogrid and isogrid, analysis is carried out with same skin and ribs dimensions, which gives the less stress and deflection in isogrid as compared to orthogrid but weight of isogrid is more. Inorder to get same weight of both structure skin thickness of isogrid is reduced and analysis is carried out which still gives less stress and deflection in isogrid structure. Therefore presently composite grid structure analysis is conducted to know the effectiveness of the isogrid and orthogrid structures in skin stiffening applications. After analysis it is found that isogrid is better than orthogrid for same weight.
