Sensitivity analysis of the scaled boundary finite element method for elastostatics
We propose a sensitivity analysis method of the scaled boundary finite element method (SBFEM) for elastostatics. We give an approach to compute the eigen-sensitivities of the Hamilton matrix. Semi-analytical evaluation of the displacement and stress derivatives. We apply it to calculate sensitivities of the stress intensity factors (SIFs) in fracture mechanics. We apply it to perform the sensitivity analysis of the orthotropic structures and cracked structures.
