Abstract: The harsh marine environment in cold regions challenges the durability of concrete columns in offshore structures. In this study, a steel fiber-reinforced cement-based composite (SFRCC) jacket is proposed to strengthen ...

Abstract: This paper first proposes a high-strength (HS) steel-moment frame structure with replaceable damage-control fuses, which utilized the very large elastic deformation capacity of HS steel and damage-control functions of ...

Abstract: Aluminum alloys (AAs) are potential alternative constructional materials for low-temperature infrastructures in cold regions and liquefied natural gas (LNG) storage tanks. This study investigated the mechanical properties ...

Abstract: To reveal the material removal mechanism of silicon carbide fiber reinforced silicon carbide ceramic matrix (SiCf/SiC) composites during the ultrasonic vibration helical grinding (UVHG) of hole-making process, a hole-making ...

Abstract: A femtosecond laser method for high-quality and high-efficiency micro-hole fabrication of SiCf/SiC composites is proposed for this difficult-to-machine material. The influence of optical wedge parameters in the femtosecond ...

Abstract: Single-crystal tungsten is widely utilized in various fields, benefiting from its outstanding properties. Nano-cutting, as an ultra-precision machining method, can realize high efficiency and low damage. However, from the ...

Abstract: A ultrasonic elliptical vibration cutting (UEVC) technique, as an advanced cutting method, has been successfully applied to machine difficult-to-cut materials for the last decade. In this study, the mechanism of the ...

Abstract: limate model simulations disagree on whether future precipitation will increase or decrease over California, which has impeded efforts to anticipate and adapt to human-induced climate change. This disagreement is explored ...
