Journal of Materials Research and Technology, 2020 The alternation of creep properties is unavoidable in welded structures after suffering from cyclic damage, which may lead to the premature failure of power plant units and hard to predict. This work is devoted to clarify the influence of prior low cycle

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Nonstructural components (NSCs) installed in large‐span reticular structures were frequently severely damaged during earthquakes, even when the primary structure remained intact. Existing seismic design specifications for NSCs were predominantly developed for upright structures such as multi‐storey buildings and offer no guidance for reticular

Influence of PWHT on the Residual Stress in Under-Matching Welded Joint
, 2015 The under-matching welded joint is commonly used in engineering practice and the postweld heat treatment (PWHT) is the common method to reduce the residual stress in the welded joint, while the research on the under-matching welded joint after PWHT is ...
