Numerical prediction of material behaviour in energetic systems at high temperature conditions

Design philosophy of many technical important constructions, including electroenergetic structure members, can be based on analytical, numerical or experimental investigations. Because of considerable interest of complex material behaviour consideration and high speed computers available, numerical procedure of material behaviour modelling is considerable. In present time optimal process design is required and in that way numerical procedure using finite element technique is the most reliable tool. The paper is focused on the development of a general numerical procedure which can be used in mathematical modelling of material behaviour under special environment conditions. For multiaxial stress or strain conditions numerical algorithm is developed using overlay technique. Computer program based on this algorithm is made and two examples are presented.
