Abstract

Present work poses, from the methodological point of view, an approach to a case offorging by indentation by means of the application of the Upper Bound Element Technique(UBET), in his development of triangular rigid blocks (TRB). With two approaches of differentnature (Modulate and not Modulate), it tackles the study of the evolution of the necessary minimumenergy to attain the required deformation. The UBET allows a suitable implementation of theboundary conditions of the process, as well as the characteristic of the same, such as the kind offriction or the geometrical considerations, without limit on the flow of material in contrary directionto the applied load by the tool.
