The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Cold‐formed steel structures around the world (2011, methodology): “Using a combination of new testing [52] and nonlinear finite element collapse analysis correct implementation of the DSM strength curves was also established; this included the use of net section yielding properties and modifications in the inelastic buckling regime for distortional buckling failure”
Aluminium alloys as structural material: A review of research (2021, background): “A numerical study on irregular-shaped sections was carried out by Chang et al. [67] who concluded that the DSM is able to predict the interactive buckling failure mode accurately but not in every case.”
