Abstract

In the past, all methods that understand deformation / fracture (D/F) characteristics have been limited on the surface indirectly. D/F characteristics are affected by micro-scale structural features like air bubbles (pores), cracks and micro-detects; therefore, they need to be analyzed inside. In this paper, we propose a system which automatically obtains the corresponding relations between pre- and post-D/F pores. Our system enables analyzing 3D, local, high-accuracy D/F characteristics. Experiments proved its effectiveness.
