摘要
基于弹性力学理论,推导出了三轴压缩试验中压缩试样的解析解.根据压缩试样的受力特点及其解析解提出了求粮食泊松比的方法和计算公式,并根据相关文献对稻谷的三轴压缩试验数据进行分析验证,结果表明该方法是可行的.
Based on the theory of elastic mechanics, an analytical solution was derived for a compress sample of triaxial compression test. According to the mechanical characteristics and the analytic solution of the compress sample, a method and a formula for calculating the Poisson ratio of grain were put forward. The experimental data of the triaxial compression test of rice was analyzed and verified according to related references, and the results showed that the method was feasible.
