Improved Equivalent Linearization Implementations Using Nonlinear Stiffness Evaluation

Improved Equivalent Linearization Implementations Using Nonlinear Stiffness Evaluation written by Stephen A. Rizzi and has been published by DIANE Publishing this book supported file pdf, txt, epub, kindle and other format this book has been release on 2001 with Random vibration categories.

This report documents two new implementations of equivalent linearization for solving geometrically nonlinear random vibration problems of complicated structures. The implementations are given the acronym ELSTEP, for "Equivalent Linearization using a Stiffness Evaluation Procedure." Both implementations of ELSTEP are fundamentally the same in that they use a novel nonlinear stiffness evaluation procedure to numerically compute otherwise inaccessible nonlinear stiffness terms from commercial finite element programs. The commercial finite element program MSC/NASTRAN (NASTRAN) was chosen as the core of ELSTEP. The FORTRAN implementation calculates the nonlinear stiffness terms and performs the equivalent linearization analysis outside of NASTRAN.

This report documents two new implementations of equivalent linearization for solving geometrically nonlinear random vibration problems of complicated structures. The implementations are given the acronym ELSTEP, for "Equivalent Linearization using a STiffness Evaluation Procedure." Both implementations of ELSTEP are fundamentally the same in that they use a novel nonlinear stiffness evaluation procedure to numerically compute otherwise inaccessible nonlinear stiffness terms from commercial finite element programs. The commercial finite element program MSC/NASTRAN (NASTRAN) was chosen as the core of ELSTEP. The FORTRAN implementation calculates the nonlinear stiffness terms and performs the equivalent linearization analysis outside of NASTRAN. The Direct Matrix Abstraction Program (DMAP) implementation performs these operations within NASTRAN. Both provide nearly identical results. Within each implementation, two error minimization approaches for the equivalent linearization procedure are available - force and strain energy error minimization. Sample results for a simply supported rectangular plate are included to illustrate the analysis procedure.Rizzi, Stephen A. and Muravyov, Alexander A.Langley Research CenterLINEARIZATION; RANDOM VIBRATION; APPLICATIONS PROGRAMS (COMPUTERS); STIFFNESS; STRUCTURAL ANALYSIS; FORTRAN; NASTRAN; RECTANGULAR PLATES; FINITE ELEMENT METHOD
