A multiaxial fatigue damage function
International Journal of Fatigue, 2007Abstract 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, 2005The 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 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, 1978Abstract 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 Fatigue Damage Models
Journal of Engineering Materials and Technology, 1987Two 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.

Multiaxial creep–fatigue rules
Nuclear Engineering and Design, 1995Abstract 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.
