Metal additive manufacturing of conformal cooling channels for improving the quality of metal injection–molded products

Advances in Mechanical Engineering
The primary advantage of metal injection molding (MIM) is that it can be used to mass-produce complex metal products; however, it requires a few secondary processes.

Discretization of Thin-Walled Sections with Variable Wall Thickness

Journal of Mechanical Engineering
At the stage of designing thin-walled aircraft structures, to simplify calculations, their cross sections are idealized. To do this, the section with the skin and the longitudinal elements reinforcing it is replaced (when determining normal stresses) by ...
