Abstract

During the service period of engineering equipment, it is very easy to suffer from the effect of accidental factors occurring local failure, and then evolved into catastrophic macro-failure. Although the current fail-safe design can resist the local failure caused by corrosion, fatigue and manual damage, it cannot resist the one caused by overloading. To solve this problem, this paper proposes a novel crack-safe design through peridynamic-based solid isotropicmaterial with penalization (SIMP) method. This method firstly utilizes the fracture simulation capability of peridynamics to obtain the most dangerous crack case of the structure through continuous iteration and fracture analysis, and then by maximizing the stiffness of the most dangerous crack case to obtain the crack-safe structure. Numerical examples show that this strategy can obtain the structural design with crack-safe effect.
