Applied mechanics of the Puricelli osteotomy : a linear elastic analysis with the finite element method
Puricelli, Edela; Fonseca, Jun Sergio Ono; Paris, Marcel Fasolo de; Sant'Anna, Hervandil Morosini (2007) [Artigo de periódico]Background: Surgical orthopedic treatment of the mandible depends on the development of techniques resulting in adequate healing processes. In a new technical and conceptual alternative recently introduced by Puricelli, ... -
Complexity control in the topology optimization of continuum structures
Cardoso, Eduardo Lenz; Fonseca, Jun Sergio Ono (2003) [Artigo de periódico]A general mesh independent filter as a mean to control the complexity of topology optimization designed structures is discussed. A new mesh-independent filter, applied over the move-limits of the sequential linear programming ... -
