Abstract: The paper presents an analysis of the influence of the compressive (vertical) component of the loading force in the wedge splitting test on the values of fracture characteristics determined using standard procedures where this component is ignored. Particularly, a portion of work of fracture due to this compressive component of loading working on vertical displacements is investigated and given into relation with the common part of work of fracture calculated in the horizontal direction only. The results show that, based on the angle and width of the wedge used in the particular WST configuration, the portion of the work of fracture due to compressive loading can be considerable and should not be neglected.

Abstract: Splitting force is the key to the process of fracture splitting connecting rod. In this paper, numerical simulation is made in the process of fracture splitting Jetta car connecting rod by using software MSC.MARC. Through analysis, the curve between J integral and splitting force is established. According to the experiential formula of impact toughness and fracture toughness, critical J integral ( JIC ) can be achieved. After getting JIC , the splitting force can be determined by linear interpolation method and verified by tensile experiment and the error is below 1%. It is proved that this method can also used to analyze other kinds of connecting rods with different materials.
