... (e.g., stress, strain, and elastic stress concentration factors) of the lack-of-fusion defects to the results of gas-entrapped pores, which share the same height and the same volume, to reveal the detriment of lack-of-fusion defects. Furthermore, we conduct a parametric study on lack-of-fusion defects...
