Multiaxial Fatigue Damage Criterion

Journal of Engineering Materials and Technology, 1988
A multiaxial fatigue failure criterion is proposed based on the strain energy density damage law. The proposed criterion is hydrostatic pressure sensitive; includes the effect of the mean stress, and applies to materials which do not obey the idealized Masing type description.

A multiaxial fatigue damage function

International Journal of Fatigue, 2007
Abstract The applicability of a non-linear Fatigue Damage Function for multiaxial fatigue strength prediction is verified for various metallic materials including mild steel, hard steel, cast iron and aluminium alloys. The proposed method determines the orientation of the critical plane which experiences the maximum quantity of damage, according to ...

Critical Planes in Multiaxial Fatigue

Materials Science Forum, 2005
The paper includes a review of literature on the multiaxial fatigue failure criteria based on the critical plane concept. The criteria were divided into three groups according to the distinguished fatigue damage parameter used in the criterion, i.e. (i) stress, (ii) strain and (iii) strain energy density criteria. Each criterion was described mainly by

Multiaxial Fatigue Damage Models

Key Engineering Materials, 2006
Two multiaxial damage parameters are proposed in this paper. The proposed fatigue damage parameters do not include any weight constants, which can be used under either multiaxial proportional loading or non-proportional loading. On the basis of the research on the critical plane approach for the tension-torsion thin tubular multiaxial fatigue specimens,

Multiaxial Fatigue Failure

1989
Multiaxial fatigue failure is caused by the propagation of cracks. Fatigue cracks may be classified as Stage I, II or III, and also divided into categories of applied multiaxial strain, Case A and Case B. Fatigue strength is a function of multiaxiality, a fact which is reflected in both the cyclic deformation response and in the various equivalent ...

Multiaxial creep-fatigue damage

Nuclear Engineering and Design, 1978
Abstract This paper presents an alternative method for extending the various methods of creep-fatigue damage assessment from the uniaxial to general multiaxial regimes. Specifically, the method gives a procedure for determining a reasonable strain range in multiaxial situations where loading may not be proportional.

Multiaxial creep–fatigue rules

Nuclear Engineering and Design, 1995
Abstract Within the UK, a comprehensive procedure, called R5, is used to assess the high temperature response of structures. One part of R5 deals with creep–fatigue initiation, and in this paper we describe developments in this part of R5 to cover multiaxial stress states.

Multiaxial Fatigue Damage Assessment

1987
This paper presents method for multiaxial fatigue damage assessment which is based on the concept of a critical plane for crack nucleation and growth. In this method, both tensile and shear growth are considered to be important. Cyclic hardening cause by out-of-phase loading is included in the constitutive equations for the stress strain simulation ...

Multiaxial Fatigue Damage Models

Journal of Engineering Materials and Technology, 1987
Two multiaxial fatigue damage models are proposed: a shear strain model for failures that are primarily mode II crack growth and a tensile strain model for failures that are primarily mode I crack growth. The failure mode is shown to be dependent on material, strain range and hydrostatic stress state.
