Use of the finite element method in studying the influence of different layers on mechanical characteristics of corrugated paperboard

Rebrasti karton se sve više traži ne samo za proizvodnju različitih pakovanja već i za izradu promidžbenih materijala, umjetničkih djela, pribora pri prijevozu skladišne robe i mnogo drugih stvari. S porastom potražnje za rebrastim kartonom javlja se i potreba detaljnijeg poznavanja njegovih mehaničkih svojstava kako bi se poboljšala kvaliteta i pouzdanost finalnih proizvoda. Korišten je model zasnovan na metodi konačnih elemenata te su analizirana mehanička svojstva slojeva rebrastog kartona i njihov utjecaj na njegova ukupna mehanička svojstva.The corrugated paperboard has become a widely used material not only for producing different packages but also for making advertising materials, pieces of art, accessories used for transportation of a number of stock items and many others. With the growing demand for corrugated paperboard comes the need for more detailed knowledge about its mechanical characteristics which would serve for improving the quality and reliability of final products. A model based on the finite element method is used to study how the mechanical characteristics of the layers of the corrugated paperboard affect its complex mechanical characteristics
