Strain energy density failure criterion

International Journal of Solids and Structures, 2001
Starting from Clausius-Duhem inequality in which the free energy depends on elastic and plastic strains, temperature, damage tensor and plastic internal variables, the author derives an intrinsic general dissipative energy density leading to a failure criterion described by the critical value of elastic strain energy density.

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 ...

Strain energy density failure criterion

1990
The selection of failure criteria for predicting the allowable load of structural components has historically been one of the problematic areas in design. The conventional approach often tends to penalize the structure in weight and size, if not economically.

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.

Energy‐Based Failure Criterion for Wood

Journal of Materials in Civil Engineering, 1994
Recent research into the strength of dimension lumber has led to the development of an alternative failure criterion based on the notion of a critical energy density for the material. The strength of wood is known to be related to the duration of an applied load; however, duration-of-load effects cannot be explained within the context of a theoretical ...

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 ...

Reliability Analysis of Mohr Failure Criterion

Journal of Engineering Mechanics, 1989
For biaxial states of stress in mass concrete structures, safety can be assessed in terms of the Mohr failure criterion. Safety is generally evaluated by a deterministic factor of safety. When loads vary and material properties are not known with certainty, reliability analysis evaluates safety probabilistically.

Three-Parameter Failure Criterion for Concrete

Journal of the Engineering Mechanics Division, 1982
A general, three-dimensional failure criterion for plain concrete and mortar is proposed. This criterion is formulated in terms of the first and the third stress invariants of the stress tensor, and it involves only three independent material parameters.
