Title: Computational procedures for determining parameters in Ramberg-Osgood elastoplastic model based on modulus and damping versus strain

Computational procedures for determining parameters in Ramberg-Osgood elastoplastic model based on modulus and damping versus strain 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.
