toppling failure is one of the most common modes of failure of rock slopes in layered rock strata. flexural toppling is one of the well-known modes of the failure. this type of failure occurs due to bending stress. in this article, a brief yet comprehensive review of toppling failure is presented. firstly, the conditions and general mechanism of the failure are described. then, experimental, th...

The present study investigates the failure mechanisms of industrial fiber materials 13 a custom designed fiber cutting performance test bench. The fracture morpholog 14 fibers are examined by scanning electron microscopy. The analysis reveals that fiber cutting can be 15 distinguished according to four distinct stages of fiber failure represented by shearing, cutting, 16 brittle fracture, and t...

In this paper, failure mechanism of a 17th stage blade of an 82.5 MW steam turbine that caused damage to the internal turbine compartment and the adjacent blade equipment has been studied. In order to determine the cause of failure and prevent similar events, various metallurgical and mechanical investigations including chemical composition analysis, metallography and microstructural analysis, ...

This paper researches two key factors (angle and thickness) of a weak layer in relation to their influencing mechanism on slope stability. It puts forward the sliding surface angle and morphological model criteria for the control of rock slopes and realization of its failure mechanism. By comparing the Failure Modes and Safety Factors (Fs) obtained from numerical analysis, the influence pattern...

Failure analysis of fractured components provides some information about the causes and conditions of fracture. Fractography is an indispensable part of the failure analysis as it is usually the only means by which the failure mechanism can be established. By using fractography, some information such as component’s life, values of the stress intensity factor and the applied stress can be calcul...
