Abstract
This chapter concerns the feature-driven optimization for structures under design-dependent loads. The implicit B-splines in closed and open forms are utilized as basic design primitives to describe the inner topology boundary and the moving pressure boundary. The design variables are associated with the shape and location parameters of the implicit B-spline curves and are thus unattached to the FE model. The sensitivities of design-dependent loads are analytically derived. The effectiveness of the presented methods is illustrated with several numerical examples.
