Survey of computer programs for solution of nonlinear structural and solid mechanics problems

Publisher Summary This chapter presents a survey of computer programs for solution of nonlinear structural and solid mechanics problems. It provides an overview of the current capabilities of 36 computer programs that can be used for solution of nonlinear structural and solid mechanics problems. These programs range from the large, general-purpose codes with a broad spectrum of capabilities, rich variety of element types, and large user community and comprehensive user support to the small and special-purpose codes with limited user community such as BEAM, BRICK, PAC78, and WHAMS. The final selection of the program to be used should be based on a detailed examination of the documentation and the literature about the program.

Recent advances in reduction methods for nonlinear problems

Status and some recent developments in the application of reduction methods to nonlinear structural mechanics problems are summarized. The aspects of reduction methods discussed herein include: (a) selection of basis vectors in nonlinear static and dynamic problems (b) application of reduction methods in nonlinear static analysis of structures subjected to prescribed edge displacements, and (c) use of reduction methods in conjunction with mixed finite element models. Numerical examples are presented to demonstrate the effectiveness of reduction methods in nonlinear problems. Also, a number of research areas which have high potential for application of reduction methods are identified.

Unilateral contact, elastoplasticity and complementarity with reference to offshore pipeline design

Abstract The purpose of this paper is to provide numerical solutions to the following problems in nonlinear structural mechanics. A slender beam with nonlinear, elastoplastic flexural characteristics is unilaterally supported in the plane by a frictionless, rigid profile. The first problem is to determine the equilibrium configuration under given vertical loads and end traction; the second, seemingly new problem is to determine the changes of the unilaterally supporting profile which reduce the curvatures of the beam below assigned values with the least total cost. Both problems arise in offshore engineering when a pipeline has to be laid on a rough seabottom, but analogous problems are found in other contexts. Approximate solution procedures are developed in view of practical applications in this context by a unified approach resting on suitable discretization (cubic splines, lumped compliance models), complementarity theory and mathematical programming. The former problem (analysis) is dealt with in the range of large displacements; geometric linearity is assumed for the latter optimization problem.

Self-correcting incremental approach in nonlinear structural mechanics.

A self-correcting, incremental-solution procedure has been developed which seems to be promising in solving geometrically highly nonlinear problems. The procedure is also applicable to systems with many degrees of freedom where the bandwidth of the stiffness matrix is large compared with the narrow bandwidth for the shell of revolution.
