The present work concerns the development of a finite element methodology for the simulation of the blade cutting of thin membranes of the type used in the carton packaging industry to seal a package containing liquid food. A new concept of “directional” cohesive element is proposed for a computationally effective simulation of this kind of problems. These elements can detect possible contact with the blade and so they transmit cohesive forces to the crack flanks in directions which may be different from the direction of the straight line connecting facing point.

Abstract
The present work concerns the development of a finite element methodology for the simulation of the blade cutting of thin membranes of the type used in the carton packaging industry to seal a package containing liquid food. A new concept of “directional” cohesive element is proposed for a computationally effective simulation of this kind of problems. These elements can detect possible contact with the blade and so they transmit cohesive forces to the crack flanks in directions which may be different from the direction of the straight line connecting facing point.File in questo prodotto:
