| Abstract: | The Semi-Analytical Element Method(SAEM)for analyzing the physical -nonlinearity mechanics of the half space is provided.The elasto-plastic stiffness matrix and the incremental-constant stiffness iterative steps for the SAEM analyzing the physical-nonlieartity problem is also given in this paper.For three-dimensional objects,the semi -analytical elements ace founded by two-dimentional analytic founctions and one-dimensional interpolating founctions. Contrasting the Finite-Element Method,the degrees of freedon of this method are reduced greatly, therefore the internal memory and the computational effort of the computer are cut down enovmously. |
