Failure Mechanism of Sumikawa Landslide

Progressive failure of a constrained creeping landslide

The ski resort town of St Moritz, Switzerland, is partially constructed on a large creeping landslide, which has been causing damage to buildings and infrastructure. At the town centre, the landslide is constrained by a rock outcrop, creating a compression zone in the sliding mass. After decades of gradual slowing down,s in the beginning of 1990s the landslide started to accelerate, in spite of...

Influence of modeling material on undercut slope failure mechanism

A series of physical modeling tests were conducted by means of a beam type geotechnical centrifuge machine in order to investigate the drainage impact on the slope failure mechanism under centrifugal acceleration. Meanwhile, the phenomenon of stress redistribution in undercut slopes and the formation of arching effect were studied. For this purpose, a poorly graded sandy soil (Silica sand No. 6...

A 3D Discrete Element Analysis of Failure Mechanism of Shallow Foundations in Rocks

In this research work, a 3D numerical modeling technique is proposed based on the 3D particle flow code in order to investigate the failure mechanism of rock foundations. Two series of footings with different geometries and areas are considered in this work. The failure mechanism obtained is similar to that of the Terzaghi’s but there is a negligible difference in between. Lastly, one equation ...

A Mechanism of Motor Failure

Fracture Failure Mechanism

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...
