Abstract:

This work expands the function of testing machines with a DOLI system, and provides a platform for teaching and research. Based on the function library of DOLI system and MFC Class Libraries provided by Microsoft, software for digital control has been developed, and measurement of the ductile fracture toughness (JIC) performed by modularized design. The software development makes use of techniques such as multi-thread, serial communication in Win32, object oriented programming, etc. The JIC of 12Cr1MoV and 20Mn steel was measured using the three-point bending specimens. The result shows that the software not only operates stably and reliably and can accurately control the testing machine in realtime, but can also measure JIC and carry out digital analysis.

Key words: digital control, measurement of JIC, software development, DOLI system
