Bandwidth optimization for rectangular matrices

In this paper a comparative study of different algorithms is provided for n odal and element ordering of finite element models. The matrix force method of structures is presented for in-plant force systems of three-node triang ular and four-node rectangular plane stress elements. Ordering algorithms f or rectangular matrices are incorporated into the turn-back approach and th e bandwidth and sparsity of self stress and flexibility matrices are compar ed through many examples. This comparison is made for plane stress finite e lement models having various configurations. (C) 1999 Civil-Comp Ltd and El sevier Science Ltd. All rights reserved.
