HB-3000C is a high precision force loading Brinell hardness
tester made in Laizhou China. HB-3000C was used to
measure some experimental blocks with different indenters,
different force levels and different load holding time.
The cylinder blocks were produced by Danqin Corporation
China, and their height and diameter are 50 mm and
100 mm respectively.
At first, we got stress–strain characteristics of the measured
blocks by a hydraulic-universal material testing machine,
as the brown curve depicted in Fig. 7. Moreover, we
described the force loading characteristics of this measurement,
as the blue dashed curve depicted in Fig. 8.
