Abstract.

A simple scheme to avoid the formation of 1-node connected hinges and checkerboard patterns in topology optimization is presented. It is formulated in terms of a single constraint that is inexpensive to compute. It is easy to incorporate in existing topology optimization implementations, and there is no difficulty in choosing the constraint value, as it should ideally be zero.
