1 ASTM E28.04 Workshop Byron Skillings, Ladish Proposed Rates: An Aerospace Perspective
2 Ladish - Common Aerospace Test Rates in/in/min to yield 0.05 in/min to fracture (ASTM E21 & Customer Req) in/in/min to yield 1 minute to fracture in/in/min to yield 0.1 in/in/min to fracture
3 Ladish - E8 Proposed Test Rates in/min to Yield Proposed yield rate 5 to 7.5 X faster 0.45 in/min to fracture Proposed to fracture rate X faster than present aerospace rates
4 Ladish - Is the change significant? Room temperature Ti testing examples
5 Ladish- Yield vs Test Rate Power Law Model
6 Ladish- Ultimate Strength vs Test Rate
7 Ladish – Yield Strength vs Ultimate Strength
8 Ladish – 0.2 Offset Yield Strength vs. Ultimate Strength
9 Ladish – Elongation vs Reduction of Area
10 Ladish – Test Summary
11 Ladish - Potential Industry Impact Design Curves Data Statistical Approvals Specifications
