Analytical Approach to the Indentation Process. Application of the Upper Bound Element Technique

Present work poses, from the methodological point of view, an approach to a case of forging 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 different nature (Modulate and not Modulate), it tackles the study of the evolution of the necessary minimum energy to attain the required deformation. The UBET allows a suitable implementation of the boundary conditions of the process, as well as the characteristic of the same, such as the kind of friction or the geometrical considerations, without limit on the flow of material in contrary direction to the applied load by the tool.
