Experimental and numerical analysis of micromechanical damage in the punching process for High-Strength Low-Alloy steels [PDF]

, 2014
Sequential sheet metal forming processes can result in the accumulation of work hardening and damage effects in the workpiece material. The mechanical strength of the final component depends on the “evolution” of these two characteristics in the ...

"Underemphasised and undervalued": ways forward for non-economic loss and damage within the UNFCCC [PDF]

, 2023
A growing body of research demonstrates the importance and prevalence of Non-economic Loss and Damage (NELD). However, little effort has been made to create policies to address NELD comprehensively within the UNFCCC.
