Structural and sensitivity reanalyses based on singular value decomposition
Structural and Multidisciplinary Optimization, 2013 The structural and sensitivity reanalysis of a structure subjected to modifications has a significant practical value. If the structural modifications result in low rank changes in the associated system matrices, the reanalysis of a structure could be completed with a computational load that is less than that of the complete analysis of the structure ...

Advanced Engineering Materials, EarlyView.Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Numerical Computation of Lower Bounds of Structured Singular Values
European Journal of Pure and Applied Mathematics, 2018 In this article we consider the numerical approximation of lower bounds of Structured Singular Values, SSV. The SSV is a wellknown mathematical quantity which is widely used to analyse and syntesize the robust stability and instability analysis of linear feedback systems in control theory.

Computational Complexity of Real Structured Singular Value in l_p Setting
, 1998 This paper studies a generalized real structured singular value (¯) problem where uncertain parameters are bounded by an ` p norm. Two results are presented. The first one shows that this generalized ¯ problem is NP-hard for any given rational number p 2

Advanced Engineering Materials, EarlyView.A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...

Generalized Numerical Range and the Computation of the Structured Singular Value.
, 1987 The concept of structured singular value was recently introduced by Doyle (Proc. IEE, vol. 129, pp. 242-250, 1982) as a tool for the analysis and synthesis of feedback systems with structured uncertainties.
