Abstract: The surface roughness of contacting parts have a strong influence on the failure form of contact fatigue. Pitting failure is liable to occur on the contact parts with rougher surface. The ...

Abstract: Under rolling-sliding contact, specimens have different failure forms, such as pitting and spalling etc. The surface roughness of specimen in contact has a strong influence on the failure form. ...

Abstract: An exact elasticity study of the free vibration of a simply-supported cross-ply cylindrical shell containing a piezoelectric layer is presented. The solution of the derived governing differential ...

Abstract: The application of intelligent algorithms in the optimal design of a membrane bioreactor (MBR) is helpful in improving reactor performance. Our study constructed a numerical flow field model of a MBR. Membrane thickness, ...

Abstract: For design-build (DB) projects, owners normally use lump sum and guaranteed maximum price (GMP) as the major contract payment provisions. However, there was a lack of empirical studies to compare the project performance ...

Abstract: Design-build (DB) is regarded as an effective means of delivering high performance green buildings, and the selection of DB contractors is of critical importance. The objective of this study is to evaluate the selection ...

Abstract: The design/build (DB) system is regarded as an effective means of delivering sustainable buildings. Specifying clear sustainability requirements to potential contractors is of great importance to project success. This ...

Abstract: Truck weight regulations maintain controls on the actual truck-load characteristics and can further affect the serviceability of constructed infrastructures. To investigate the truck weight regulations of small- to medium-span ...

Abstract: The toll-adjustment mechanism (TAM) is a hybrid of a price cap regulation mechanism and a revenue sharing mechanism. It is one solution to saving private investors from severe traffic demand risk and the government from ...
