Weight Optimum Design of Pressurized and Axially Loaded Stiffened Conical Shells to Prevent Stress and Buckling Failures

An optimal design of internal pressurized stiffened conical shell is investigated using the genetic algorithm (GA) to minimize the structural weight and to prevent various types of stress and buckling failures. Axial compressive load is applied to the shell. Five stress and buckling failures as constraints are taken into account. Using the discrete elements method as well as the energy method, ...

Finite element analysis of stiffened plates

The paper presents the development of a new plate/shell stiffener element and the subsequent application in determine frequencies, mode shapes and buckling loads of different stiffened panels. In structural modelling, the plate and the stiffener are treated as separate finite elements where the displacement compatibility transformation takes into account the torsion – flexural coupling in the s...

Optimal Topological Design of Stiffened Plates Using the SRV Constraint for 0/1 Solutions

1. Abstract This paper applies optimum structural topological design methodologies to the stiffening of plates in bending. The purpose of the design is to use a given amount of material as orthogonal stiffeners to minimize the compliance of plates in bending. Cheng and Olhoff had shown that if left unchecked, this formulation includes dense sets of infinitely thin stiffeners – a solution though...

design and weight optimization of pin loaded composite plates

in design and optimization process of laminated composite structures, the number of layers, layer angles, stacking sequence, material types and etc should be specified. each of aforesaid parameters can be applied as a design variable. in this paper the target is to minimize the weight of laminated composite pin loaded structures. the laminated composite structures are designed based on the load...
