      Cylic type of loading is not supported for J-Integral. The J-integral method is developed based on domain integral method. In other words, loading must be monotonic. In the case of cyclic loading, there is a unloading process after plastic deformation, making the energy density non-unique function of mechanical strain. Therefore, the techniques used to compute J-integral becomes invalid. This is the main reason why J-integral is incorrect for cyclic loading.
