【 摘 要 】

A nonclassical mechanical model for the process of additive manufacturing a bearing circular conical pillar by means of its layer-by-layer thickening over the lateral surface using a viscoelastic aging material under simultaneous action of an axial variable central force is developed. The exact in the sense of Saint-Venant principle analytical solution of the stated corresponding quasi-static boundary value problem is constructed. The obtained solution allows to retrace the evolution of the stress-strain state of the manufactured pillar after the start and on completing the piecewise continuous additive process under consideration.
