Static collapse: A survey of methods and modes of behavior
TL;DR: In this article, a survey is given of plastic buckling behavior, which spans three areas: asymptotic analysis of postbifurcation behavior of perfect and imperfect simple structures, general nonlinear analysis of arbitrary structures, and nonlinear collapse at the maximum point in a load versus deflection curve.
Journal ArticleDOI
Structural optimization using beam elements
TL;DR: In this paper, the complexities of evaluating the geometrical properties of a section, stress recovery, and variable selection are successfully handled by the concept of an element library, use of equivalent stress, and separation of sensitivity variables and design variables.

Hongmei Li,Jorge Carballido,Harry H. Yu,Vladimir Okhmatovski,Elyse Rosenbaum,Andreas C. Cangellaris +5 more
TL;DR: In this article, a new and efficient method is introduced for the calculation of the Green's function that can accommodate arbitrary substrate doping profiles and thus facilitate substrate noise analysis using boundary element methods.

Sizing Design Sensitivity Analysis of Dynamic Frequency Response of Vibrating Structures
Kyung K. Choi,Jae Hwan Lee +1 more
TL;DR: In this article, a variational approach with a non-selfadjoint operator for complex variable is used to retain the continuum elasticity formulation throughout derivation of design sensitivity results, and a numerical implementation method of continuum design sensitivity analysis results is developed using postprocessing analysis data of COSMIC/NASTRAN finite element code to get the design sensitivity information of displacement and stress performance measures of the structures.
