ABSTRACT
Separating, Morphing, Adaptive, and Remeshing Technology (SMART) was released in ANSYS190 to simulate the fatigue crack growth, in which crack growth is governed by Paris’ Law. In this chapter, SMART was used to simulate the crack growth in mini dental implants (MDIs). The computational results illustrate that the stress intensity factor K1 at the crack front kept path-independent during the crack growth. The crack growth at the various loading steps was plotted. The relationship between the cycle numbers and crack extension was obtained. This study demonstrates the capability of SMART. As opposed to the eXtended Finite Element Method (XFEM), which is another approach to simulate crack growth, SMART requires the creation of an initial crack in the geometry, and then the performance of the remeshing during the crack growth. However, SMART works for all kinds of meshing, especially free meshing that dominates in the practical problems.
