[en] Comparison of the results of finite element (FEM) analyses were made with actual test data on prestressed concrete beam models. The ADINA computer program was used to perform the analyses with two material models for concrete. One material model was the concrete model furnished with ADINA and the second was the endochronic model as added by D.N. Fanning at Oak Ridge. Results of the prestressed concrete beam tests were compared to ADINA FEM results for both the regular and the endochronic material models. Published results of concrete specimens tested in uniaxial, biaxial, and triaxial states of stresses were collected and reduced to computer data files. The data files were then used to compare with results predicted by the endochronic theory in another computer program. The results of these comparisons, the source of the reference material, and a plot of the comparisons are included. A total of thirty two files were created in this phase of the study
