The Effects of Steel Core Imperfection, Gap Size and Friction Coefficient on the Behavior of All-Steel Buckling Restrained Braces

open access: yesDüzce Üniversitesi Bilim ve Teknoloji Dergisi, 2021
Buckling restrained braces (BRBs) which are generally composed of a steel core and a encasing(buckling restrainers) are utilized to resist lateral forces in high seismic regions since BRBs exhibit high energy dissipation capacity, ductility and stiffness.

ON THE IMPERFECTIONS OF CRYSTALS [PDF]

open access: yesProceedings of the National Academy of Sciences, 1929
Imperfections of crystals may be either of mechanical or chemical nature. As will appear in the course of this investigation, the phenomena related to the chemical imperfections can hardly be understood without a preliminary knowledge of the mechanical defects of the crystals considered.
