Razvoj in testiranje izdelkov potekata vedno pogosteje v virtualnem okolju, kjer simulacije potekajo na podlagi matematično-fizikalnih modelov in lastnosti izdelkov, med katere spadajo tudi elasto-plastične lastnosti materiala. Cilj naloge je preveriti izvedljivost identifikacije le-teh z uporabo di ...

Za zagotovitev točnega izračuna mehanskega odziva izdelka je treba v izračunu upoštevati čim bolj realen odziv materiala, ki ga popišemo s konstitutivnim modelom. Za določitev parametrov modela se v zadnjem času uporablja metode inverzne identifikacije na podlagi nehomogenih polj deformacij. V delu ...

In designing high-performance, lightweight components, cellular structures are one of the approaches to be considered. The present study aimed to analyze the effect of the infill line distance of 3D printed circular samples on their compressive elastic behavior. Lightweight cellular poly-lactic acid ...

This paper aims to compare different heterogeneous test designs from the perspective of the confidence interval quantification of inversely identified parameters, where the influence of a DIC optical system systematic and random error are taken into account. Because the errors in optical measurement ...

Conventionally, plastic anisotropy is calibrated by using standard uniaxial tensile and biaxial test results. Alternatively, heterogeneous strain field specimens in combination with full-field measurements can be used for this purpose. As reported by the literature, such an approach reduces the numb ...

Digital image correlation (DIC) is a powerful tool for characterising materials and determining material model parameters. To assess the reliability of the full-field measurement-based inverse identification procedures, it is crucial to investigate the impact of the measurement errors on the identif ...

Quadruple glazing has become a high-end standard in the field of sealed insulating glass units. With more than three glass panes a set of internal heat-related technical problems emerges. Durability, being the most pressing problem, requires careful management of the primary sealant deformation, esp ...

In the area of glazing façades and windows, the increasing environmental demands have boosted the development of insulating-glass units (IGUs). There is already 4–6 pane glazing on the market, with heat transmittance U$_{cw}$ < 0.40 W/m$^2$K, which offers exceptional energy efficiency and living com ...

Pseudobrookites (Fe$_2$TiO$_5$-FeTi$_2$O$_5$) are promising candidates for high-temperature oxide thermoelectrics. In this work, we used natural Fe-Ti-rich heavy mineral sand (HMS) as an abundant and environmentally friendly raw material for the preparation of pseudobrookite-based ceramics. The main ...
