The roughening of free surface during plastic forming of metals, such as metal forming, is an important problem from a standpoint of surface finishing of the products as well as the fracture of the sheet metal. In the present paper, an analytical study is made of the relation between surface roughening and inhomogeneity of plastic deformation, especially for a range of relatively small strains. In order to simulate surface roughening, a model of inhomogeneous material is employed and elastic-plastic deformation of the model material is calculated by the finite element method. Based on the result of calculation, an equation is proposed which expresses the effect of strain, grain size and mode of deformation on the surface roughening.
