Abstract: The paper presents a nonlinear fracture mechanics analysis of mixed-mode fracture and anchor pullout in concrete. The analysis is based on elements with inner softening bands (ISB). A major advantage of the ISB approach ...

Abstract: A 30-year retrospective analysis of resource use in a range of new construction and repair projects reveals insignificant productivity increase when applying traditional narrow measures, as shown in a case study of beam ...

Abstract: The tiny contact zone (approximately 1 cm2) where steel wheel meets steel rail is fundamental to rail transport. This work is a comprehensive presentation of recent research in wheel–rail contact tribology. It stresses ...

Abstract: The contact surfaces in a boundary lubricated spherical roller thrust bearing can change form due to sliding and particle generated wear. These form changes can seriously reduce the fatigue ...

Abstract: Recently, much attention has been paid to the influence of airborne particles in the atmosphere on human health. Sliding contacts are a significant source of airborne particles in urban ...

Abstract: Successful completion of a construction project requires the ability to coordinate activities of numerous individuals participating in tasks that often have high levels of complexity and uncertainty. Thus, the project ...

Abstract: A majority of the machining processes in the industry of today are performed using position-controlled machine tools, where conservative feed rates have to be used in order to avoid excessive process forces. Instead of ...

Abstract: Product and process platforms have been promoted as possible enablers of increased productivity in civil engineering. However, such platforms are traditionally applied in mass manufacturing industries where production ...

Abstract: A controller for critical vehicle maneuvering is proposed that avoids obstacles and keeps the vehicle on the road while achieving heavy braking. It operates at the limit of friction and is structured in two main steps: a ...
