| Abstract: | In the teaching of material mechanics,the drawing,compression,twisting,bending and various sorts of combination experiment are indispensable. In this paper, one kind of multi-functional material mechanics experimental system has been designed to implement different loading modes and all kinds of experiments. The system has ten channels of strain measurements and 1 channel of stress measurement,and it uses SCM and analog/digital converter to construct high-precision circuit. Serial-port is used to communicate with the computer and real-time data collecting and processing can be realized. |
