Empirical methodology to determine inherent strains in additive manufacturing [PDF]
Computers & Mathematics with Applications, 2019 Part distortion is a critical issue during Additive Manufacturing (AM) of metallic parts since it prevents this technology from being implemented at industrial level. To this regard, distortion prediction even from design stage has become crucial. Actually, numerical modelling methodologies play an important role here.

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.
