【Abstract】 An elaborate dual reciprocity boundary element formulation for axisymmetric problems has been derived. A new function f was proposed to eliminate the singularity on symmetric axis in the original function f used in published papers. The new function f was successfully used to calculate some transient heat conduction and moving boundary condition with phase change.更多还原
