Abaqus Analysis User's Manual Vol 2
Damage initiation refers to the onset of degradation at a material point. In ABAQUS the damage initiation criteria for fiber reinforced composites are based on Hashin's theory (see Hashin and Rotem, 1973, and Hashin, 1980). These criteria consider four different damage initiation mechanisms: fiber tension, fiber compression, matrix tension, and matrix compression.

A consequence of the above choice is that plastic flow results in inelastic volume expansion in the tensile region and no inelastic volume change in the compressive region.

Introduction to fatigue An early example of testing to determine the fatigue strength of a component was reported by W.A.J. Albert in 1838. He investigated the fatigue failure of chains used to haul trucks in mine shafts (Ref 1.1).
The initiation criteria have the following general forms:

is a coefficient that determines the contribution of the shear stress to the fiber tensile initiation criterion; and
are components of the effective stress tensor, , that is used to evaluate the initiation criteria and which is computed from:
where is the nominal stress and is the damage operator:, , and are internal (damage) variables that characterize fiber, matrix, and shear damage, which are derived from damage variables , , , and , corresponding to the four modes previously discussed, as follows:Prior to any damage initiation and evolution the damage operator, , is equal to the identity matrix, so . Once damage initiation and evolution has occurred for at least one mode, the damage operator becomes significant in the criteria for damage initiation of other modes (see “Damage evolution and element removal for fiber-reinforced composites,” Section 19.3.3, for discussion of damage evolution). The effective stress, , is intended to represent the stress acting over the damaged area that effectively resists the internal forces.

An output variable is associated with each initiation criterion (fiber tension, fiber compression, matrix tension, matrix compression) to indicate whether the criterion has been met. A value of 1.0 or higher indicates that the initiation criterion has been met (see “Output” for further details). If you define a damage initiation model without defining an associated evolution law, the initiation criteria will affect only output. Thus, you can use these criteria to evaluate the propensity of the material to undergo damage without modeling the damage process.
