Elastic plastic transient mechanical analysis and LCF assesment of the demining tool tiller

The paper presents finite element analysis of fracture behavior of the shaft demining tiller tool. On the costumer request tiller shaft was made from non-alloy structural steels. Transient elastic plastic mechanical analysis and Low cyclic fatigue (LCF) analysis was performed for shaft with high strength steel and non-alloy structural steels. Assessed critical locations are prevented form cracking by adapting design. Optimized design of tiller shaft fulfills required lifetime and brings significant lower price and simpler production.
