Abstract

The mixing of hard inclusions into materials is one way to strengthen and increase the durability of the materials, creating granular composite materials. However, apart from the hard inclusions in material, other impurities (soft inclusions) and holes still have the ability to appear and affect the durability of the material. The existence of holes, impurities will affect the behavior of the crack. In this paper, the authors will investigate the effects of holes, hard inclusions, soft inclusions on the behavior of crack when growing under the effect of dynamic loads by extended twice-interpolation finite element method-XTFEM. The results of the dynamic stress intensity factor obtained from numerical examples will clearly show the impact of different types of particles on cracks... The results obtained by XTFEM will be compared with the results published in a prestigious international scientific journal to verify reliability.
