Failure mode and effects analysis by data envelopment analysis

Decision Support Systems, 2009
Failure mode and effects analysis (FMEA) is a method that examines potential failures in products or processes and has been used in many quality management systems. One important issue of FMEA is the determination of the risk priorities of failure modes.

The stability of slopes in soils with nonlinear failure envelopes

Canadian Geotechnical Journal, 1984
The failure envelopes of many soils are significantly nonlinear and the effect of this curvature on slope stability is examined. Charts, based on circular arc stability analyses, have been prepared and make possible the rapid assessment of the stability of slopes of simple geometry in uniform soils with curved failure envelopes.

Linearizing Triaxial Test Failure Envelopes

Geotechnical Testing Journal, 1981
Abstract Soil variability biases both the best-fit-by-eye and linear regression of p-q triaxial test data plots (where p represents the abscissa of the center of a Mohr circle and q is the radius) to substantially over-estimate the friction angle ø.

Determination of shear failure envelope in rock masses

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1986
In this work, an analytic expression has been developed that enables the shear strength to be determined using the empirical failure criterion developed by Hoek and Brown. Applying this new hypothesis, along with elasticity theory and basic mathematical concepts for obtaining the failure envelope of a family of failure circles, the shear strength has ...

Failure envelopes for caisson foundations in calcareous sediments

Applied Ocean Research, 1998
Caisson or bucket foundations are being used increasingly for offshore developments, in soil conditions ranging from soft clay to dense sands. This paper addresses the performance of caisson foundations in fine-grained calcareous soil, under combined vertical (V) and horizontal (H) loading.

Failure envelopes of mudrocks at high confining pressures

Geological Society, London, Special Publications, 1999
Abstract Whereas models for the mechanical behaviour of many types of sedimentary rocks at high mean effective stresses (2–50 MPa) are now reasonably well developed, few attempts have been made to generate models for mudrocks in the same way.

Fitting failure envelopes by the method of least squares

Quarterly Journal of Engineering Geology, 1983
Summary A proposed form of Mohr's failure criterion is shown to reduce, under certain conditions, to several classical failure criteria. The failure envelope for each criterion is then determined using the method of least squares.

Shape of the failure envelope for a jointed rock specimen

Quarterly Journal of Engineering Geology, 1987
The purpose of this Technical note is to draw attention to an important result that is the consequence of testing specimens of rock large enough to approach the rock mass properties rather than the rock material properties usually determined on smaller specimens; it is based on some recent work carried out at the Transport and Road Research Laboratory.

A Comparative Study of Failure Envelopes in Composite Laminates

Journal of Reinforced Plastics and Composites, 1983
On the basis of a recent survey conducted by AIAA composite structures subcom mittee, the failure criteria used by more than ninety percent design engineers have been considered in this study. These failure criteria are maximum stress, maximum strain and quadratic polynomial (Tsai Wu, Chamis, Hoffman and Hill) failure criteria.
