Abstract:
A method,called the Consistent Tangent Stiffness Method (CTSM),isproposed in this paper.we apply CTSM to the solution of three-dimensional elastoplas-tic problems.The method satisfies the complementary criteria of loading and unloading.and furthermore it is characterized by the advantages of preserving the asymptotic rateof quadratic convergency,consuming less computational tinie, holding the first order ac-curacy and unconditional stability.The problems of slow convergence and low accuracy,which have exist...
