Numerical Analysis Programming on the Concrete Elastic-Plastic Behavior

Using arc-length method, the progress of solving nonlinear function is discussed for designing new numerical analyzing tool, and the frame of programming based on nonlinear method is compiled. The results from completely restricted modeling show convex deformation and the damage on oblique section. And with the concrete elastic-plastic constitutive used in numerical simulation including add uninstall, typical engineering examples inspect reliability of the elastic-plastic numerical analysis program. This provides the basis and guidance for the future of the specific program design.
