In the course of designing and testing a PV fabricated from Ti-6Al-4V Titanium, we have experienced several catastrophic failures which seem to indicate that the material is reacting to stress concentration as a brittle material. Has anyone experience with this alloy?
I am presently in the process of designing a pressure vessel for sonar equipment to be used in depths up to 6km. After extensive manual calculations and FEA analysis we fabricated parts from the Ti-6Al-4V titanium alloy and experienced several catastrophic failures in testing, which seem to...
I am in the midst of designing a titanium pressure vessel to be deployed at a 6km (8800 psi) depth and needs to have a FOS of 1.25 minimum. The design as it now exists has an ID of 4.375" and a wall thickness of .302" and an unsupported length of 16.7". Most of the critical design equations for...
