Traction Method
This paper describes the numerical method for domain optimization problems based on the traction method. The traction method was recently proposed as a solution to domain optimization problems.With the traction method,the domain variation is analyzed under a condition where the objective functional decreases.We propose a convenient numerical method using a genaral purpose FEM to apply the traction method to practical problems. The domain optimization problem treated here is a mean compliance minimization problem of linear elastic structures.The computed results of a multiply connected plate and a solid torsion bar are compared with those obtained by other authors.The practical application of the method is also demonstrated with a plane sample and a solid one.The results show sufficient validity of the proposed numerical method for practical domain optimization problems.
