In practice, the submarine's major internal equipment is mounted to welded plating foundations, but submarine designers have been looking at the recent French innovation whereby the major internal equipment is mounted to a large truss/cradle structure through point supports. The focus of this research investigates the effects of radial point supports on the stability behavior of cylindrical she...

The recently developed Spring Back Reflector has low stiffness in the deployed configuration. A general method of stiffening this type of reflector without changing its folding properties is presented. The stiffening is achieved by adding a conical skirt around the edge of the dish; this skirt snaps elastically when the dish is folded. The paper concludes that it is possible to design spring ba...

Mao-tai lees (ML) is a by-product produced in the process of liquor production and contains high levels crude protein, starch fiber, large yield. Thus, ML has potential to become feedstuffs alternatives livestock production. The present study evaluated nutritional values fermented (FML), including first stage (FML I; microbial fermentation), second (FMTL II; final (FFML; fermentation with prote...

Fiber metal laminates (FML) are composite structures consisting of metals and fiber reinforced plastics (FRP) which have experienced an increasing interest as the choice materials in aerospace automobile industries. Due to a sophisticated built up material, not only design production such is challenging but also its damage detection. This research work focuses on identification FML with guided ...

In the present work, an optimization method is proposed in order to produce innovative stiffening layouts for large stiffened cylindrical shell structures, as they appear aerospace industry. A component-based logic applied on a ground mesh of structural elements (shells and beams), which was inspired by techniques explicit topology solid (plane or tridimensional massive models). Geometric compo...

PANDA2, a computer program for the minimum-weight design of elastic perfect and imperfect stiffened cylindrical panels and shells under multiple sets of combined loads, is used to obtain optimum designs of uniformly axially compressed elastic internal T-ring and external T-stringer stiffened cylindrical shells with initial imperfections in the form of the general buckling mode. The optimum desi...
