Slab Method and Experimental Analysis of Indentation Forging of Tubes

In this paper, Generalized slab method (GSMA) is used to study the indentation forging of thick walled tubes. Axisymmetric slab model is developed to study the effects of various parameters such as lubrication and thickness of tube on the loads required for feeding the tool inside the tube. Various mandrel geometries are considered. Experiments are carried out to verify the model and reasonable agreement between experimental and analytical results is observed.
