| Abstract: | In this paper,several axisymmetric thermal problems which have different boundary
condtions are calculated by the BEM with isoparametric quadratic boundary elements.A
non-homogeneous problem is studied,and the effects of a number of elements and a num-
ber of Gauss points are studied,too.At last a calculating result of a gas turbine disc is ex-
pressed. |
