The precise time-domain expanding BEM is presented for solving the non-Fourier heat conduction problems with laser heat sources.Firstly,by expanding physical quantity of time-dependent at any one of the discrete time interval,the recursive formulation of the governing equation is obtained.Then,a recursive boundary integral equation is derived by the weighted residual method,where the radial integral method is used to transform the domain integral into the boundary integral.Also,after the boundary integral equation is discretized by BEM,a self-adaptive judging criterion is used in the solving process.
