Abstract We consider a family of three-dimensional stiffened plates whose dimensions are scaled through different powers small parameter $\varepsilon $ ε . The plate and the stiffener assumed to be linearly elastic, isotropic, homogeneous. By means $\Gamma Γ -convergence, we study asymptotic ...

This paper aims at investigating the optimum location of a single longitudinal stiffener having various cross-section types steel plate girders subjected to bending loading. The is found using gradient-based Interior-Point (IP) optimization algorithm. procedure involves linear elastic buckling analysis with finite element method, which coupled aforementioned IP algorithm and used calculate coef...

By extending the work published at ICCS 2020 [1], in this paper we propose a method to achieve cost-effective 3D printing of stiffened thin-shell objects. Our proposed consists three parts. The first part integrates finite element analysis, Voronoi diagram, and conformal mapping obtain stiffener distribution. second combines analysis with optimization calculations determine optimal sizes stiffe...
