static (“Static stress analysis,” Section 6.2.2) with both XFEM and the conventional finite element methods;

quasi-static (“Quasi-static analysis,” Section 6.2.5) with the conventional finite element method only;

steady-state transport (“Steady-state transport analysis,” Section 6.4.1) with the conventional finite element method only;

coupled thermal-stress procedures (“Fully coupled thermal-stress analysis,” Section 6.5.4) with the conventional finite element method only; and

crack propagation (“Crack propagation analysis,” Section 11.4.3) with the conventional finite element method only.

Contour integrals can be requested only in general analysis steps: they are not calculated in linear perturbation analyses (“General and linear perturbation procedures,” Section 6.1.2).

A crack analysis with pressure applied on the crack surfaces may give inaccurate contour integral values if geometric nonlinearity is included in a step.

Loads

Contour integral calculations include the following distributed load types:

thermal loads;

distributed loads, including crack face pressure and traction loads on continuum elements as well as those applied using user subroutine DLOAD and UTRACLOAD;

distributed loads, including surface traction loads and crack face edge loads on shell elements as well as those applied using user subroutine UTRACLOAD;

uniform and nonuniform body forces; and

centrifugal loads on continuum and shell elements.
