The process of steel pouring in ceramic mold with different pouring rates is under consideration. The system of differential equations, which describe mold elastic deformations, was constructed and solved by approved numerical method with heat conduction equation, initial and boundary conditions. Results of the computation are analyzed. Mold failure criterion in earliest time stations is suggested.
Keywords: investment casting, mathematical modeling, numerical outline, ceramic shell molds, stressed state.
