Correct consideration of the service load effects plays a very important role on assessment of railway bridges, especially on fatigue assessment.Eurocode EN 1991-2 introduces twelve types of service trains and prescribes their sequel in normal and heavy duty.The click here service trains, consisting of locomotive and defined number of wagons, are s
This research work is devoted to the simulation of a steel-belted radial tire under different static loads.The nonlinear finite element calculations were performed using the MSC.MARC code, installed on a computer system equipped with a parallel processing technology.Hybrid elements in conjunction with two hyperelastic models, namely Marlow and Yeoh
The prospect of physical exertion commonly acts as a deterrent to the adoption of cycling for everyday transport.A battery powered assistance torque electric motor could alleviate such physical exertion by reducing the effort required by the cyclist.This study investigates the potential effectiveness, efficiency, and energy saving of electrically-a
Prevention of high-risk human-wildlife and human-human interactions, which can accelerate the occurrence of future outbreaks, epidemics or pandemics, requires global efforts.These efforts should focus on reducing the risk of contact with wildlife, pre-outbreak surveillance of wildlife and high-risk people, improvement of wildlife trade biosafety, a
