Corner Elimination in Discrete Topology Optimization of Compliant Mechanisms

Abstract

State of material can be either void or solid in the optimization of discrete topologies. In the present discrete topology optimization, one main issue is the unsmooth boundaries. These are created due to subdivision techniques and exist as sharp corners in the topology solution. Even though outer corner cutting and inner corner filling method can reduce the corners, it cannot completely eliminate them. Corners that are at 90° are reduced to 135° using the corner handling
