Study on Dynamic Measurement of Thermal Stress during Solidification of a Casting Specimen

Abstract:

Article Preview

A method was presented for the indirect measurement of dynamic stress of casting in this paper. A stress sensor embedded in the sand mold close to the casting was used to reveal the pressure resulted by the shrinkage of casting which could figure out the dynamic stress of the frame-shaped casting indirectly. The numerical simulation was also carried out by FDM/FEM method. The results showed that the pressure grew up quickly in the rapid cooling period and then kept on a steady value. The experimental and calculated results were in good agreement.
