    Abstract

    Residual stresses take place mainly due to unequal changes of volume and non-simultaneous phase and structural changes in different parts of the casting. If stresses exceed tensile strength of the component in production or service, deformation or cracking of the casting will happen. To avoid casting defects, it is necessary to know how big the residual stresses are and if they surpass the allowed values. In this paper determination of residual stresses in stress lattice with simulation software device are presented. These simulations confirm previous researches on the influence of mold thickness on the occurrence of residual stresses in the stress lattice. From the representation of the dependence of residual stresses on the thickness of the mold, it can be concluded that with increasing thickness of the mold, the residual stresses decrease. The greater the thickness of the mold causes a slower cooling which results in less residual stresses in the stress lattice.
