A Failure Criterion for Concrete

Journal of the Engineering Mechanics Division, 1977
A four-parameter failure criterion containing all the three stress invariants explicitly is proposed for short-time loading of concrete. It corresponds to a smooth convex failure surface with curved meridians, which open in the negative direction of the hydrostatic axis, and the trace in the deviatoric plane changes from almost triangular to a more ...

Modified failure criterion for shales

, 2013
Most shale rocks which contain an appreciable fraction of reactive clays (e.g. Montmorillonite) will adsorb drilling mud filtrate (water+ions) and cause unstable drilling conditions. When contacted with the mud filtrate, these shales will swell, creating

PREDICTION OF LAMINATE FAILURE WITH THE ROTEM FAILURE CRITERION

Composites Science and Technology, 1998
The mechanical behaviour of four types of composite material in various laminate lay-ups is examined by using the Rotem failure criterion. The criterion distinguishes between fibre failure and matrix failure. Only in-plane loads are considered, neglecting the possibility of interlaminar failure.

An energy criterion for fatigue failure

Strength of Materials, 1993
A criterion for the fatigue failure of metals is presented which is based on specific energy dissipation during the loading cycle. Equations are obtained which determine the relative critical failure energy for cyclically unstable materials. The parameters used were studied as functions of the mean stresses.

Criterion for fatigue failure in steels

Technical Physics Letters, 1999
A formal criterion for fatigue failure in steels, which permits reliable detection of the transition to the final stage of the process on the basis of the form of the dependence of the propagation velocity of ultrasonic waves in them on the number of loading cycles and the derivatives of this function with respect to the number of cycles, is ...
