OPTIMIZATION OF CORRUGATION PATTERN ON CORRUGATED SHELLS

نویسندگان

چکیده

The folded plate structure is a structural form that increases bending rigidity and strength by folding the plate. When plane bent in waves, in-plane stiffness wave orthogonal direction, but extremely decreases because meandering like spring direction. Since shell structures resist external forces mainly forces, it considered there an appropriate arrangement of corrugations according to flow when surface made into corrugated improve performance.

Buckling Analysis of Axially Loaded Corrugated Cylindrical Shells

Buckling analyses of heavily corrugated cylindrical shells based on detailed full finite element models are usually computationally expensive. To address this issue, we have proposed an efficient computational method of predicting the onset of buckling for corrugated cylindrical shells which builds on the Bloch wave method for infinitely periodic structures. We modified the traditional Bloch wa...

Experimental Heat Transfer Studies of Water in Corrugated Plate Heat Exchangers: Effect of Corrugation Angle

In the present investigations heat transfer studies are made in three different types of corrugated plate heat exchangers having a length of 30 cm and width of 10 cm. The corrugated channel has a spacing of 5 mm. Three different corrugation angles are used in this study which are 30 0 , 40 0 and 50 0 . Water is taken as test fluid as well as the heating medium. The wall temperatures are measure...

Multiscale Mechanics and Optimization of Gastropod Shells

A vast majority of mollusks grow a hard shell for protection. The structure of these shells comprises several levels of hierarchy that increase their strength and their resistance to natural threats. This article focuses on nacreous shells, which are composed of two distinct layers. The outer layer is made of calcite, which is a hard but brittle material, and the inner layer is made of nacre, a...

Structural Optimization of Free-Form Grid Shells

In the 21 st century, as free-form design gains popularity, free-form grid shells are becoming a universal structural solution, enabling merger of structure and façade into a single layer – a skin [1]. This paper shows some of the results of a research project concerned with the optimization of grid structures over some predefined free form shape, with the goal of generating a stable and static...
