Investigation Die Profile Effect on Nosing Process Using Finite Element Method

Darya Sarwar Mohammed Salih, Azal Rifaat Ismail


The study aims to use the finite element analysis in nosing process. After making a preliminary study on the shell nosing parameters, two conical die with semi-die angles (10°, 20°) have been designed and simulated using the (ANSYS 5.4) software package. The process has been carried out using pure Aluminum shells of (1.5, 3, 4.5) mm thickness under conditions of cold and hot nosing process at (400 C°), specimens having a diameter (50) mm and length (100) mm. The nosing process involves implementing two dies (10°, 20°) using pure Aluminum shells of (3, 4) mm thickness with several speeds and with a mixture of oil and graphite as lubrication, a good agreement is obtained between the experimental work and the simulation. It is noted that the best die is conical die with (10°) die semi angle.
