Causes of Catastrophic Failure of High Mn Steel Utilized as Crusher Overlaying Shields (TECHNICAL NOTE)
The secondary cone crusher's shields at Sarcheshmeh Copper Complex of Iran are made of Hadfield steel with a nominal composition of Fe-1.3 % C-12 % Mn. They have a cut-off in the shape of a cone with an upper end diameter of 80cm and an approximate lower end diameter of 200 cm whose main problem is an unexpected early failure under normal working condition. In this paper, the results of metallo...
متن کاملMitigating Catastrophic Failure at Intersections of Autonomous Vehicles (Short Paper)
Fully autonomous vehicles promise enormous gains in safety, efficiency, and economy. Before such gains can be realized, safety and reliability concerns must be addressed. We have previously introduced a system for managing such vehicles at intersections that is capable of handling more vehicles and causing fewer delays than traffic lights and stop signs [2]. While the system is safe under norma...
متن کاملCatastrophic Failure and Critical Scaling Laws of Fiber Bundle Material
This paper presents a spring-fiber bundle model used to describe the failure process induced by energy release in heterogeneous materials. The conditions that induce catastrophic failure are determined by geometric conditions and energy equilibrium. It is revealed that the relative rates of deformation of, and damage to the fiber bundle with respect to the boundary controlling displacement ε₀ e...
متن کاملRecurrent Catastrophic Ceramic Femoral Head Failure in Total Hip Arthroplasty
Fracture of a modern ceramic head component in total hip replacement is an uncommon but catastrophic complication. Hence, the occurrence of a second ceramic head fracture in the same hip replacement of an individual represents a perishingly rare event. We present the case as a means of highlighting potential risk factors for ceramic head fracture and suggest possible management strategies in su...
متن کاملInvestigation of non-catastrophic failure mode observed in SiC diodes
Power devices are widely used for the power handling portion of the electronic devices for space systems as well as ground-based commercial devices. In our previous study, we investigated the fatal destruction mode called single-event effects (SEEs) in the SiC schottky barrier diode (SiC-SBD) and SiC metal-oxide-semiconductor field-effect transistor (SiC-MOSFET). SiC is expected to be a candida...
