Query: Topological synthesis of fluidic pressure-actuated robust compliant
  mechanisms   This paper presents a density-based topology optimization approach for
synthesizing pressure-actuated robust compliant mechanisms. To ensure
functionality under manufacturing inaccuracies, the robust or three-field
formulation is employed, involving dilated, intermediate and eroded
realizations of the design. Darcy's law in conjunction with a conceptualized
drainage term is used to model the pressure load as a function of the design
vector. The consistent nodal loads are evaluated from the obtained pressure
field using the standard finite element method. The objective and load
sensitivities are obtained using the adjoint-variable approach. A
multi-criteria objective involving both the stiffness and flexibility of the
mechanism is employed in the robust formulation, and min-max optimization
problems are solved to obtain pressure-actuated inverter and gripper compliant
mechanisms with different minimum feature sizes. Limitations of the linear
elasticity assumptions while designing mechanisms are identified with high
pressure loads.
