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.
