A modified leaky ReLU scheme (MLRS) for topology optimization with multiple materials

作者：

Highlights：

• A modified leaky ReLU scheme (MLRS) for topology optimization with multiple materials is proposed.

• A sequence of modified leaky ReLU functions are used for the material property interpolation.

• No extra design variables will be introduced when implementing MLRS for multiple material topology optimization.

• The sensitivity of objective and constraint functions is easy to derive.
