A Design Approach for Complex Stiffeners [PDF]
, 2000 This paper presents a design approach for laterally braced cold-formed steel flexural members with edge stiffened flanges other then simple lips. The design method for flexural members given by Schafer and Pekoz (1999) is used here for designing these ...

A Level-Set-Based Density Method for Buckling Optimization of Structure with Curved Grid Stiffeners
Applied SciencesCurved grid stiffeners, compared to straight stiffeners, offer greater flexibility in adjusting the force transmission paths and give better structural performance. In this paper, a level-set-based density method is employed to generate layouts of curved

Advanced Functional Materials, EarlyView.Melanin content directly controls fungal spore mechanical properties, with pigmented spores achieving rupture forces two orders of magnitude higher than hyaline spores. Environmental stress drives this quantity‐quality tradeoff; stressed species invest energy in melanin‐reinforced, mechanically superior thick‐walled, super‐hydrophobic spores, while ...

Automated design of aircraft fuselage stiffeners using multiobjective evolutionary optimisation
, 2020 This paper proposes an optimisation process for the design of aircraft fuselage stiffeners using evolutionary optimisation. A new design problem is developed to find a layout for fuselage stiffeners (rings and stringers) such that the structural mass ...

Genetically Programmed Shape‐Morphing of Engineered Living Materials
Advanced Functional Materials, EarlyView.Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with

Optimization of hybrid I-beams using modified particle swarm method
Инженерно-строительный журнал, 2018 An approach for the optimization of hybrid welded I-beams based on the modification of the particle swarm method is proposed. A solution search is performed on discrete sets of variable parameters, which are taken as the size of sheets of rolled steel ...
