This paper presents several finite element analyses on a dent produced by a single shot. A finite element model is discussed in order to clarify the influences of peening conditions and characteristics of material on the surface aspect. The following points are presented; (1) Dent form is influenced significantly by the yield stress of work material, but not influenced by density and Poisson's ratio. (2) Influence of Tangent modulus on the Dent form, which is work hardening coefficient, is low whenever Yield stress is high. (3) Finite element analysis method (FEM) is able to represent almost exactly dent forms.
