Limitations of the inherent strain method in simulating powder bed fusion processes

Additive Manufacturing, 2018
Abstract Process optimization has always been a crucial step for effective usage of metal additive manufacturing (AM) processes: it consists in establishing quantitative relations between final part's characteristics and process parameters to find their optimal combination and obtain a fully functional mechanical component. Experimental investigation

Photo-induced copper-catalyzed sequential 1,n-HAT enabling the formation of cyclobutanols

Nature Communications, 2021
Cyclobutanols are difficult structures to access given their inherent ring strain. Here, the authors present a method to form substituted cyclobutanols from a photocatalytic cascade reaction, proceeding via a 1,5- or 1,6-hydrogen atom transfer and ...

Cracking prediction at solid-tooth support interface during laser powder bed fusion additive manufacturing

Journal of Science: Advanced Materials and Devices, 2023
Cracking resulting from residual stress at the solid-tooth support interface frequently occurs in laser powder bed fusion (LPBF) metallic additive manufacturing, and thus it is critical to predict possible cracking and design the support to prevent it ...

Measurement of Welding Residual Stresses of Reactor Vessel by Inherent Strain Method

QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 2007
The objective of this study is to ensure safety of nuclear reactors. A few accidents of leaks from welded zones at pipe penetration parts of reactor vessel or in coolant pipes have been reported around the world. One of the main causes of such leaks is welding residual stress.
