Current and future trends in topology optimization for additive manufacturing (2018, methodology): “Some important applications in this field include maximization of the critical load of a continuum structure with large displacement by Kemmler et al. (2005), consideration of hyperelastic bodies with non-zero prescribed displacement by Klarbring and Strömberg (2013) and topology optimization of sna”
Level‐set topology optimization with many linear buckling constraints using an efficient and robust eigensolver (2016, methodology): “A well-known issue in topology optimization involving linear buckling is the occurrence of spurious modes in the void region of the design space [11, 12].”
Topology optimization of continuum structures under buckling constraints (2015, background): “However, as the introduced parameter ql plays a critical role in avoiding the appearance of pseudo modes, using an improper value may lead to erroneous results [19,20].”
