Computational properties of titanium using finite element prediction and experimental result

Titanium and its alloys are is widely used nowadays especially in aerospace applications, automobiles, building equipments and many more. Since, it was an expensive material, less research have been done to determine their actual properties. Finite Element (FE) method was applied to investigate response of titanium under different conditions. Computational model was developed in ALGOR FE code. The best model was choosen through mesh convergency analysis. Tensile experiment was carried out on ASTM standard titanium specimen and stress strain response was also obtained experimentally. The computational model was then validated with the experimental results. The results were found to be agreeable in terms of stress strain response both in elastic and plastic regions with error less than 2%. Further simulation were carried on with different strain rates. Stress strain response of titanium under different strain rates shows that strain increase monotonically at increased rate. Computational model can be used to economically determine material response under various conditions
