Abstract: To extend the application of large increment method (LIM) into 2D solid analyses, a 4-node quadrilateral element which adapts to LIM was proposed. Two numerical examples were solved  using the new element. The mesh convergence and the insensitiveness to the mesh distortion are proved, and the advantage of parallel computation is implied.  

Key words: general inverse force method, large increment method, finite element method, quadrilateral element
