Pri obravnavi ulitkov se večina dosedanjih raziskav omejuje le na vpliv posameznih, izoliranih por. Ta doktorska naloga se zato osredotoča na slabše raziskano področje vpliva obsežne makro poroznosti na dobo trajanja. Gre za celovito raziskavo pogosto uporabljene aluminijeve zlitine v livarski indus ...

In real engineering applications, machine parts are rarely completely homogeneous; in most cases, there are at least some minor notch effects or even more extensive inhomogeneities, which cause critical local stress concentrations from which fatigue fractures develop. In the present research, a shif ...

The objective of this research is to present the development of an innovative tree protection structure. With the increasing population of wild animals, the number of tree trunk damages is rising. Similarly, frequent damages occur during intensive forestry operations and timber harvesting, where bar ...

The static and low-cycle durability of three planar cellular structures, hexagonal, auxetic and auxetic-chiral, have been compared. The three structures have the same critical cross-section and are made from an aluminium alloy Al7075-T651. The reference region of each structure is represented by a m ...

The purpose of the article is to present a design of an active composite cellular structure, which consists of two different materials. A flexible polymer matrix is moulded around a pre-braided wire reinforcement, which is made of a high-strength shape memory material NiTi SMA. The composite is form ...

The development, production and application of an active hybrid cell structure are presented. The composite structure is built from two very different materials, the combination of which enables changing the external geometry of the product with a temperature variation. The base (matrix) is a biodeg ...

In the article, the low-cycle fatigue life durability of thin-plate auxetic cellular structures is compared with the thin-plate specimens of standard shape. Both the re-entrant auxetic cellular structures and the standard specimens were cut from a 2mm-thick strip of aluminium alloy 7075-T651. First, ...

The fatigue life of a high-pressure die-cast alloy, AlSi9Cu3, with significant porosity is investigated. Standard specimens were cyclically loaded (R =-1) until fatigue rupture occurred. The specimens were [micro]-CT scanned to obtain a 3D representation of the pores. Models were used to computation ...
