Project 2 Online experimental scheme design software The online experimental scheme design system, in the material mechanics experiment, is equipped with a combination test bench to develop an online experimental scheme design system. The software contains twelve experimental projects and can be combined with more than 50 experimental protocols. Using this software for program design, multiple experimental programs can be designed for the same experimental project. For each scheme, different devices, test pieces, and measuring points should be analyzed and selected; different strain gauges, compensation methods, bridge connections, bridge arm coefficients; different leverage ratios, loading methods; different stress states, calculations formula. After a series of analysis choices, an experimental scheme is formed and printed out. This experimental scheme design system is the first in China.
