Abstract
One of the prominent advantages of the recently developed scaled boundary finite element method is its capability of calculating stress intensity factors (SIFs) directly from the stress solutions, as stress singularities at crack tips are analytically represented. This advantage is used in this paper to calculate dynamic SIFs by the analytical Frobenius solution to the governing nonhomogeneous differential equations in the frequency domain, which is developed and presented in the accompanying paper. A benchmark problem of dynamic fracture mechanics is modelled. The material internal damping is considered by a complex modulus. It is shown that employing the new Frobenius solution, the scaled boundary finite element method is able to predict accurate frequencydynamic SIFs relations effectively and efficiently.
