This work studies the non-linear behavior of a clayey Iraqi soil taken from Baghdad city, using bounding surface plasticity model under static and dynamic loadings.There is a necessity to provide and determine the properties and the input parameters that the bounding surface plasticity model required in order to use them in non-linear soil behavior analyses under static and dynamic conditions. Site investigation is carried out and undisturbed samples are obtained.The soil test results are used in a computer program named EVAL to compute the soil properties and input parameters that are required in the bounding surface plasticity model. After input parameters became available, one could use them in finite element computer programs for static and dynamic analyses. Two-finite element programs are chosen. One for static analysis and the other for the dynamic one. The first program, named ACED used for solving coupled problems under static loading. While second program, named DLEARN, is used for solving a one-dimensional problem under sinusoidal loading and a two-dimensional problem of San Fernando dam under an earthquake load.
