Dynamic Stress Intensity Factor of Fixed Beam with Several Notches by Infinitely Similar Element Method
The dynamics stress intensity factor of fixed specimen with several notches was analyzed by semi-analytic method. The semi-analytic formula was taken as the interpolation function near notch tip and the degrees of freedom near notch tip were transformed into a small set of generalized coordinates by means of the series expansion formulas of the displacement field. The dynamics stress intensity factor for fixed specimen with two notches or cracks under centralized loading and well-proportioned loading was obtained. The results show that the KI and KII are existed at the same time for fixed specimen with several notches under dynamics loading.
