Piercing soft solids: A mechanical theory for needle insertion
Stefano Fregonese, Mattia Bacca
In this paper we investigate the mechanical problem of piercing a soft solid body with a needle. This phenomenon is controlled by the critical condition of needle insertion. Needle…

How friction and adhesion affect the mechanics of deep penetration in soft solids
Stefano Fregonese, Mattia Bacca
The mechanics of puncture and soft solid penetration is commonly explored with the assumption of frictionless contact between the needle (penetrator) and the specimen. This leads t…
