Abstract A calculation model of stress field in laser additive manufacturing of walnut shell composite powder (walnut
shell/Co-PES powder) was established. The DFLUX subroutine was used to implement the moveable application
of a double ellipsoid heat source by considering the mechanical properties varying with temperature. The stress
field was simulated by the sequential coupling method, and the experimental results were in good accordance with
the simulation results. In addition, the distribution and variation of stress and strain field were obtained in the
process of laser additive manufacturing of walnut shell composite powder. The displacement of laser additive
manufacturing walnut shell composite… More >
