The finite element method (FEM) was used for numerical simulation of stress and strain distribution in V-notched specimens, as well as for the prediction of life time of springs, considering the selected leaf spring geometry, mechanical properties of steel and conditions of fatigue. The determination of Sf of spring steels, as well as FEM-based simulation of the notch effect in specimens and Nf prediction of leaf springs was presented. The calculated life-time of the springs is in a good agreement with its real life time obtained with the structural testing of actual leaf springs for trucks.

Computer modeling and simulation of metallurgical processes can significantly simplify and improve the development and manufacture of a new product. Forging industry Unior Zreče already regularly uses a FEM based computer tool DEFORM for the development and construction of new forging dies. In this contribution, usability of heat-treatment module for the the simulation of heat-treatment of hot forging dies is presented. A comparison between FEM simulations and the experimental results is made.
