Take-up faktor kao koreolacijska vrijednost geometrije vala i čvrstoće konstrukcije ambalaže od valovitog kartona

Denis Jurečić, Darko Babić, Tigran Jokić

U radu je opisan utjecaj geometrije vala na čvrstoću i krutost ambalaže od valovitog kartona. Valoviti sloj sastavljen je od zakrivljenih lukova i ravnih segmenata. Rezultati ispitivanja čvrstoće i krutosti valovitog kartona s odgovarajućim profilom vala korišteni su za procjenu prosječnih svojstava naprezanja i deformacija u ambalaži od valovitog kartona. Matematičkim modelom dobiven je TAKE-UP faktor koji predstavlja optimalnu vrijednost između odabira geometrije vala i njegova utjecaja na čvrstoću konstrukcije ambalaže s jedne i troška proizvodnje s druge strane.

The take-up factor as a correlation value of the wave geometry and corrugated cardboard wrapping material construction strength

Denis Jurečić, Darko Babić, Tigran Jokić

The paper describes the influence of the wave geometry on thecorrugated cardboard wrapping material strength and toughness. The corrugated layer is composed of curved arches and flat segments. The results on testing corrugated cardboard strength and toughness with a corresponding wave profile were used for evaluating average stress and deformation characteristics for corrugated cardboard wrapping material. The TAKE-UP factor was derived on basis of the mathematical model and it represents the optimal value between choosing the wave geometry and its influence on the wrapping material construction strength on one side, and production cost on the other side.

Key words: wave geometry, corrugated cardboard, wrapping material, take-up factor

Patrik Ervells latest collection is ironically titled “Software”ADIDAS ORIGINALS TUBULAR SHADOW. In the notes from the presentation, Ervell says he was interested in developing tension between nostalgia and sci-fi,NIKE ZOOM WINFLO 3 and even included 90s cyberpunk amongst his influences. Ervell developed this point of view by creating an imaginary software company called Idegen software systems. He then re-appropriated the company’AIR JORDAN XXXI MENs logo in several of the collection’s garments. Elsewhere,MBT TARIKI MEN mohair coats with oversized lapels made an appearance alongside mock neck tees,NIKE AIR JORDAN RETRO 5 police-inspired ribbed sweaters,MBT FORA GTX WOMEN flight bombers, and polyurethane leather coats. The setting was also suitably dystopian, and the resulting ambiance was something akin to if the creators of Deutschland 83 and Hackers met up and decided to create a collection… We mean that as a compliment.Yesterday afternoon,JORDAN CP3 IX MEN artist JR spent the day working on his latest collaborative piece with Daniel Arsham in Greenpoint,NIKE AIR MAX 90 Brooklyn,MBT KIMONDO GTX MEN NYC. Connecting the lines between art, architecture, dance and theater, Daniel Arsham has been known to subvert existing architectural structures in unconventional,NIKE CLASSIC CORTEZ NYLON playful ways; confusing and confounding the expectations of space and form.
