Originální abstrakt

An important phase of the bolt production is a bolt head trimming. It is a very fast, complicated process including material failure. For this type of problems the explicit solvers are widely used. The calculations presented in this paper were performed by software PAMCRASH, version 2005.1. Finite element models were created using two types of material model with fracture mechanism, strain limit model and EWK model. In the next phase the experiment was carried out. The behaviour of the cutting force and the look of the separated material were evaluated. The results compare two computational material models to each other with a help of number of eliminated elements and contact force behaviour. The comparison of the cutting force of EWK model and experiment is presented as well.
