Failure Modes of Asperities in Rock Discontinuities
… work has proven the significant role of tensile failure in fracture process of asperities under direct shear loading. The result of this work can be combined with future research to develop a more meaningful relationship between the peak shear strength of the rock joints and the applied normal …

A study of localized failure modes in brittle materials
Localization studies arise from the need to accurately model the behaviour of materials which exhibit instabilities due to strain softening or geometric effects. Localization in finite element modelling of brittle materials such as concrete and rock is a relatively unexplored area in computational …

A systems approach to mitigation of project failure modes
… approach towards the mitigation of project failure modes. The methodology used is the application of the Scope and Solution Neutrality principle to develop a general model for Project Systems using the Object- Process-Method (OPM) for systems modeling. By correlating the elements and …

Approximations to worst-case data dropping: unmasking failure modes
A data analyst might worry about generalization if dropping a very small fraction of data points from a study could change its substantive conclusions. Checking this non-robustness directly poses a combinatorial optimization problem and is intractable even for simple models and moderate data sizes. …

Planar metallization failure modes in integrated power electtonics modules
… different materials. This may result in unknown failure mechanisms in power applications. Extensive research has already been done to study the performance, processing, and reliability of the planar interconnects in thin film structures. The thickness of the thin films used in integrated circuits …

Failure modes of silicon nitride rolling elements with ring crack defects
… influence and the fundamental mechanism of the failures they cause. The purpose of this study is to examine the contact fatigue failure modes of silicon nitride rolling elements with surface ring crack defects. In this study, new experimental and computational techniques are developed to measure …

Finite element analysis of failure modes in dynamically loaded pre-cracked steel plates
… stresses considered to be responsible for two modes of failure: opening crack inclined at 70°, and shear crack inclined at -5° to the notch ligament. At small impact speeds and large notch tip radii failure in the 70° direction is due to the high tensile hoop stress. At high impact speeds and …

Case study of Cape Wind : identifying success and failure modes of offshore wind projects
… years ago was not a major cause for the to date failure of Cape Wind. Rather, it is the level of advocacy against the project at its beginning that has the most impact on its overall timeline. Major efforts should therefore be devoted to defuse the most vehement opponents right from the …
