Design Dependent Loads

In this paper, topology optimization of structure subject to design-dependent loads is studied. The position and direction of the design-dependent loads will change as the shape and topology of structure changes during optimization iteration. A potential function is introduced to locate the surface boundary. Design sensitivity analysis is derived. Examples from the proposed method are presented.

In this paper firstly a new hypothetical model of bone remodeling based on bone bioactivity mechanism and Turing reaction-diffusion equations is presented. Secondly this model of bone remodeling is translated to material formation and resorption process of continuum structures, a new heuristic structural topology optimization is presented. Finally short cantilever beam problem, one of the widely used examples in structural topology optimization are carried out by using present method to confirm the validity of the proposed topology optimization method.
