Deformation Prediction of Plate Line Rolling Forming Based on Inherent Strain Method [PDF]

open access: yesMathematical Problems in Engineering, 2017
Inherent strain method has been widely used as a forecasting and computing method for welding deformation of large complicated structures and further applied to the research of line heating forming. Mechanical forming is a common ship‐hull plate forming method, for which deformation prediction still depends mainly on elastoplastic finite element method.

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

open access: yesNature 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

open access: yesJournal 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 ...
