A density-based floating projection topology optimization (FPTO)   method will be presented. The formation of a solid/void topology in FPTO   attributes to the floating threshold of the projection, rather than the   well-known penalty scheme in the solid isotropic material with penalization   (SIMP) method. The basic idea of the FPTO method is to tune design variables as   close to solid or void as possible by the floating projection, meanwhile   maintain the objective function being minimum. The capability of the floating   projection in achieving a solid/void design is discussed. Apart from the   compliance minimization problem, the effectiveness of the FPTO method has also   been demonstrated on a series of extended topology optimization problems, such   as multiple displacement constraints, frequency optimization and the design of   compliant mechanisms. The proposed FPTO method avoids the potential difficulty   in selecting an artificial material interpolation scheme.
