Abstract:Prispevek obravnava izpeljavo tristraničnega projektnega elementa za uporabo pri optimalnem projektiranju oblike konstrukcij. Osnova za izpeljavo novega elementa je tristranična Bézierjeva ploskev, ki je običajno parameterizirana z uporabo težiščnih koordinat. V prispevku je uporabljena drugačna parameterizacija, ki je bolj prilagojena postopkom optimizacije oblike. Na podlagi te ploskve je definiran projektni element-Bézierjevo telo, katerega mreža nadzornih točk ima v tipološkem pomenu obliko tristranične prizme. Uporaba izpeljanega elementa je ponazorjena na dveh številčnih zgledih.

Title:Structural shape optimization: a trilateral design element
Abstract:This paper considers the derivation of a trilateral design element for the shape optimization of structures. The element derivation is based on a trilateral Bézier patch, usually being parameterized by barycentric coordinates. Here, another type of parameterization is used, which is more convinient for employment in optimization procedures. Based on this patch the design element is derived-a Bézier body whose control points represent a trilateral prism in the topological sense. The use of the derrived element is illustrated by two numerical examples.
