Abstract: Precast concrete segmental bridge columns (PCSBCs) have developed rapidly in recent years. To study the effect of shear on the carrying capacity of the joints in PCSBCs, four conventionally reinforced concrete segmental ...

Abstract: In order to enhance the machinability of SiCp/Al composites and improve the surface quality after machining, a laser-ultrasonic vibration-assisted machining (LA-UVAM) method is presented. In order to investigate the ...

Abstract: Multi-axis electrical discharging machining (EDM) is the main manufacture method for shrouded blisks, which are key components of aero and rocket engines. Involving both linear and rotational axes, a feeding path for ...

Abstract: This paper studies the problem of geometric constraint acquisition from a given planar motion task using Fourier descriptor. In the previous work, we established a computational geometric framework for simultaneous type ...

Abstract: The traditional material constitutive model can effectively simulate the mechanical properties during the cutting process. However, the scale characteristics contained in materials are not considered in the traditional ...

Abstract: In this paper, the first principle method based on density functional theory is adopted to establish the interface model of WC/WC-Co through the software Materials Studio (MS). On the basis of this interface structure, ...

Abstract: To deal with class imbalance learning (CIL) problems, a novel algorithm is proposed based on kernel extreme learning machine (KELM), named KELM-CIL. To solve it, two algorithms are developed from the dual and primal spaces, ...

Abstract: To investigate the mechanism for the enhanced load-bearing capacity of stud connectors owing to an increase in concrete strength, the push-out test is analyzed using nonlinear finite-element (FE) models. A distinct failure ...
