A new multi-material level set topology optimization method with the length scale control capability (2018, unknown): “Lund [14] employed the DMO for multi-material shell laminate design to maximize the buckling load factor.”
Discussion on some convergence problems in buckling optimisation (2008, background): “Besides buckling optimisation, difficulties of convergence may appear when vibrations or vibration-type instabilities such as flutter are studied ( Haftka and Starnes 1974; Seyranian 1982; Guo et al. 2005).”
Optimization formulations for the maximum nonlinear buckling load of composite structures (2011, background): “…Hu and Wang (1992); Walker et al (1996); Mateus et al (1997); Walker (2001); Foldager et al (2001); Hu and Yang (2007); Topal and Uzman (2008); Lund (2009); Topal (2009), have considered buckling optimization of composite structures where the buckling load was determined by the solution to…”
A bi‐value coding parameterization scheme for the discrete optimal orientation design of the composite laminate (2012, background): “It is necessary to mention the work of Lund and co-workers [11-13] who proposed s series of parameterization schemes to treat the laminate design of composite materials as a discrete material optimization (DMO) problem.”
Stacking sequence and shape optimization of laminated composite plates via a level-set method (2016, background): “There are however a few works on topology optimization applied to fiber orientation tailoring of laminated composites, carried out by Lund and his co-workers [34, 40, 46, 54, 66] and also by [12, 18].”
Level‐set topology optimization with many linear buckling constraints using an efficient and robust eigensolver (2016, methodology): “Instead, a linear buckling analysis [8, 9, 10, 11] or a geometrically nonlinear analysis [8, 12] is used to compute the critical buckling load.”
Optimization strategies for discrete multi-material stiffness optimization (2011, methodology): “This approach has been applied successfully to material distribution problems with criterion functions such as maximization of structural stiffness, eigenfrequencies and buckling loads, see e.g. the references above and Lund (2009) .”
SFP—a new parameterization based on shape functions for optimal material selection: application to conventional composite plies (2011, methodology): “In their recent work, Lund and coworkers [9-14] have proposed the Discrete Material Optimization (DMO) approach to parameterize the topology optimization problem of structures made of fibers reinforced composite materials.”
