Introduction to the Special Issue on Recent Developments of Isogeometric Analysis and Its Applications in Structural Optimization.

An editorial is presented on the Isogeometric analysis (IGA), which aims at integrating CAD and CAE models, is one of the most active research topics in both computational mechanics and computer-aided geometric design. The rapidly growing interests in IGA has led to profound developments of relevant theories and applications, one of which being structural optimization with the rapid growth of researches in IGA.
