Summary

In this paper, we analyse specimen properties of so-called Drop Weight Tear Test (DWTT), which is often used for a fracture resistance evaluation in material engineering. Our goal is ductile and brittle fracture area detections in 3D DWTT surface scan by Lloyd type algorithms, i.e. k-means, k-medians and PAM. For correct evaluation of 3D scan of DWTT surface, we consider new concept of DWTT surface normal vector characteristics, which is presented in our previous works. Further, we take into account efficient parallel MPI implementation of Lloyd solvers and their testing. Benchmarks and the achieved clustering result evaluations conclude the paper.
