Abstract

For the finite element analysis of nonlinear problems, the displacement controlled method (DCM) has a more extensive application scope and a more powerful ability than the load controlled method (LCM) in common use. However, due to difficulties of DCM in solving procedure, the application of DCM in geomechanics has been restricted.By means of Sherman Morrison theorem,the solving procedure of DCM needs only little computation but has very good numeric stability. Moreover, the program structure of DCM is as simple as that of LCM.
