Experimental and numerical simulation of tensile behavior and failure of titanium alloys under simulated SPF post-processing conditions

Three titanium alloys were tested in tension after simulated SPF exposure to three different temperatures and subject to three different post-processing methods. This paper presents an experimental analysis and numerical simulation of the mechanical behavior of post processed and as exposed titanium material. Stress versus strain curves, necking behavior and final fracture results were simulated using finite element modeling techniques and correlated to the experimental results. The simulations were able to predict experimental results in most cases.
