Abstract null null Corrosion in roll coolant tank is a rare phenomenon in the steel industry. The ability of the cold rolling emulsion to prevent corrosion on the cold rolled steel, the mild steel coolant tank, the mill housing and pipelines stems from the presence of oil soluble corrosion inhibitors, anti-oxidants or anti-wear additives present in rolling oil formulation. During normal operational conditions, the mill coolant (mixture of oil and water) along with the generated iron fines is con...

Abstract null null Reinforced concrete flat slabs (FS) are sensitive to punching shear failure. Such failure may progress to the slab loss of supports and its downwards motion that is followed by its impact with the slab underneath. This slabs impact may initiate a progressive collapse of the entire building. The design guidelines provided by modern standards to avoid punching shear failure and to prevent post-punching loss of slab support in an attempt to prevent progressive collapse are based ...

Abstract null null Thermal deformation of the cylinder liner (TDCL) and the temperature–viscosity effect (TVE)of the lubricating oil are two common thermal effects which impact the lubrication properties of the piston-ring–liner tribological pair. In this study, the influence of these two thermal effects in a low-speed two-stroke diesel engine on piston ring lubrication performance are discussed in detail. For the TDCL, a steady-state heat-transfer model based on sequential fluid–solid coupling ...

Abstract null null An automobile company provides quality assurance service based on warranty period, which includes duration and distance driven. The concerned automobile company provides a warranty that begets quality assurance costs in case an accident occurs during this time. If the probability of failure can be ascertained based on the quality assurance area, it will be convenient to manage each part, and it will reduce the cost of quality assurance. It has been reported that failure data i...

Abstract null null This paper presents a unified electromechanical modeling framework of a single-stage spur gear with cracks at tooth root. The model has been developed following modified Lagrangian approach with the consideration of Rayleigh dissipative potential. The coupled electromechanical equations of motion represent a non-autonomous system. Improved analytical model based time-varying mesh stiffness (IAM-TVMS) at different crack depths is incorporated in the developed model to examine t...

Abstract null null The purpose of this work is to analyze the damage of AISI D2 punch head whose main part is used halting production. The punch head failure could be categorized into three major types namely the swollen, the mated and the cracked punch. Furthermore, this study underlines the punch damage causes using the optical microscope and SEM so as to check and characterize the microstructure of cracks. In this respect, EDS was used to inspect corrosion, then XRD and micro hardness were ut...

Abstract null null Railway axles are designed to be highly reliable so as to ensure even more than 30 years of service. Even though they are periodically inspected by scheduled Non Destructive Testing (NDT) inspections to detect the potential initiation of cracks, failures with disastrous consequences for railway vehicles and human beings can occur. null This paper reports an investigation concerning the failure of an axle of a passenger coach due to fatigue crack propagation. Calculations indic...
