Abstract:

An extended finite element method for two dimensional ten, perature field problems is proposed. The method is characterized by utilizing the information from nodes in external elements to construct approximate functions on the element without additional nodes and elements, the computational accuracy can be improved by the technique.

Key words: finite element analysis, temperature field, numerical computation
