A formulation is presented for the shape modification under equality and inequality constraint conditions which are expressed in linear form of design variables. Slack variables are introduced to modify the inequality conditions into the equality form. The formulation is based on the solution of the governing equation of the design variables and slack variables by means of Moore-Penrose generalized inverse. The complementary solution is added when the partidular solution fails to satisfy the requisite of the slack variables. Numerical examples based on the boundary element sensitivity analysis deal with the shape modification of a press yoke aiming at light-weight design under stress restriction and verify the validity of the proposed formulation.
