Numerical analysis and geometric optimization of perforated thin plates subjected to tension or buckling

Thin perforated plates when employed in naval, marine and offshore structures are used as a way of access or to reduce the total weight of the structure. If these perforated plates are tensioned, regions of stress concentration are generated. If these panels are subject to a compressive load, the bu...

Summary:Thin perforated plates when employed in naval, marine and offshore structures are used as a way of access or to reduce the total weight of the structure. If these perforated plates are tensioned, regions of stress concentration are generated. If these panels are subject to a compressive load, the buckling phenomenon can occur. The objective of this paper was to perform a geometric optimization based on the Constructal Design method for these structural elements. The computational models were developed in the ANSYS software. The results indicated optimal geometries 2700 % and 74 % superior for tension and buckling applications, respectively.
