Sensitivity and design of fiber layout in composites
For a linear structure reinforced with elastic fibers, the first variation of an arbitrary behavioral functional corresponding to variation of shape or orientation of fibers is derived by using the direct approach to sensitivity analysis. The relevant optimality conditions for optimal design and identification problems are then derived. Both the static and dynamic loading cases are considered. Some simple examples illustrate the applicability of the presented approach.
