Abstract | A general purpose finite element program for structural engineering was developed with linear and fully non linear static capabilities. The nonlinear capabilities include the implementation of load control, displacement control, and arc-length control algorithms. A gradient ratio is introduced to measure the curvature of the equilibrium path. By using the gradient ratio as a guiding parameter, the main equilibrium path ca n be traced by automatic stepping algorithm. Employing the unified control method and macro-command concept, the user is free to select and design his own so lution steps. XFEAP86 is a micro version of the software developed under the above criteria, and is working under MS - DOS operating system. Several numerical examples show that the automatic arc-length control algorithm is the most effective among the above three tracing methods ; and microcomputers have a high potential for developing large scale finite element analysis package. |
