Prediction of metal creep behaviour used in building energetic systems using finite element method

A large number of engineering systems operate under multiaxial stress conditions and at the same time under special environment conditions. Because of the fact that optimal procedure design, based on the design specifications will dictate the design life under such mentioned conditions, it is of transcending importance to make an analysis of the time-dependent effects such as creep and relaxation. The paper deals with the numerical modelling of creep behaviour of the building energetic structure members which operate under special environment conditions. Mechanical sublayer method using finite element procedure is used. Using viscoplastic models two applications are presented.
