Resumen
This present research work deals with the analysis of the design of different specimen geometries so that by finite volume
simulations, the appearance of cracks may be predicted in the case of forging processes. To this end, each of the geometries
selected are studied by means of compression tests between plane shape dies in the same conditions (T = 25 ºC). On the one

This present research work deals with the analysis of the design of different specimen geometries so that by finite volume
simulations, the appearance of cracks may be predicted in the case of forging processes. To this end, each of the geometries
selected are studied by means of compression tests between plane shape dies in the same conditions (T = 25 ºC). On the one
hand, a value for the critical damage value is obtained by applying the Cockroft-Latham’s criterion and on the other hand, a
damage distribution along all the specimen volume with the aim of defining a specimen which shows the most likely place for the
crack to appear. This crack location may be also determined through visual inspection with the aim of being able to evaluate this
experimentally in the near future. [--]
