Abstract
A rigid-plastic finite element method which is based on the upper bound theory in plasticity is applied to the study of deformation behavior of inhomogeneous materials with inclusions. The penalty method and the Newton-Raphson's repeated calculation are adopted to minimize the functional and to obtain the solution. Characteristics of the deformation behavior of inhomogeneous material with inclusions are discussed based on the calculated results.
