本文编制了计算机程序RAMBO，根据不同剪应变下的剪切模量和阻尼比数据，计算Ramberg-Osgood弹塑性模型中的参数。本报告中给出了为确定模量和阻尼比与剪切应变的数据或关系的最佳拟合找到参数的基础和程序。对Ramberg-Osgood关系式进行了重新整理，使计算结果与模量和阻尼比的数据拟合得更好。对模型中的数据约束进行了讨论。
A computer code, RAMBO, is developed for obtaining the values of parameters in the Ramberg-Osgood elastoplastic model based on data of shear modulus and damping ratio at various shear strains. The basis and procedures for finding the parameters for the best fit of the data or relations defining modulus and damping ratios versus shear strain are given in this report. The Ramberg-Osgood relationship is rearranged so that the results can best fit data of both modulus and damping ratio. Constraints of data in the model are also discussed.
