A New Approach For Calculating Inherent Strain and Distortion in Additive Manufacturing of Metal Parts [PDF]

The International Journal of Advanced Manufacturing Technology, 2021
Abstract Additive manufacturing (AM) of metallic parts is widely utilized for industrial applications. However, quality issues of the printed parts, including part distortion and cracks caused by high temperature and fast cooling, result in high residual stress. This is a challenge that limits the industry acceptance of AM.
