Abstract: With the indenter scratches the single-crystal, polycrystalline and polycrystalline-twin structures CoCrFeNiCu, these characteristics in various crystal nanostructures were found. Single-crystal structure CoCrFeNiCu has ...

Abstract: Local defects, such as surround cavities and insufficient thickness of the tunnel lining due to imperfect construction, will lead to local discontinuity in the ground–lining interaction. This study investigated the mechanical ...

Abstract: Resistance factors are used to account for the uncertainties associated with pile resistance in load and resistance factor design (LRFD). Current design codes and most previous studies recommend a single resistance factor ...
