On the properties of the concave antiprisms of second sort / O osobinama konkavnih antiprizmi druge vrste
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2013)
The paper examines geometrical, static and dynamic properties of the polyhedral structures obtained by folding and creasing the two-rowed segment of equilateral triangular net. Bases of these concave polyhedra are regular, ...
3D lattice panels based on the concave polyhedra of the second sort: ideas for architectural ornaments
(Beograd: Fakultet primenjenih umetnosti, Univerzitet umetnosti u Beogradu, Srbija, 2019)
Concave polyhedra of the second sort (abbreviated: C-II-n) constitute a group of polyhedra formed over regular n-sided base polygons and having a deltahedral lateral surfaces. This group includes: concave cupolae, concave ...
Generating a Type of Concave Cupolae of Fourth Sort
(Timişoara: Editura Politehnica, 2013)
The paper discusses the generation of a specific group of polyhedra, Concave Cupolae of Fourth Sort (CC IV) with regular polygonal bases, using constructive and analytical procedures. Beside determination of the parameters ...
