By combining the Bodner-Partom constitutive model and equivalent stress function, finite element methods and program on analyzing non-elastic deformation and stress for thermal viscoplastic material are studied in this paper, and it’s the first time that this material model is used in a kind of engineering software-MARC. Thermal viscoplastic behavior of high temperature alloy GH536 specimen with gap is analyzed by this program. The research results show it is feasible to analyze thermal viscoplastic behavior of specimen or structure by applying B-P model.
