Abstract
The matching of constraint between laboratory specimens and actual cracked structures is a key problem of the accurate structure integrity assessment. Different laboratory specimens and the steam turbine blade with different constraints were selected, the matching of constraint between steam turbine blade and laboratory specimens was investigated. The results shown that the steam turbine blade with 2c = 50 mm, a/2c = 0.20 has a matching constraint with single edge-notched bend specimen with a/W = 0.6 and single edge-notched tensile specimen with a/W = 0.3. The steam turbine blade with 2c = 50 mm, a/2c = 0.25 has a matching constraint with single edge-notched bend specimen with a/W = 0.7. The steam turbine blade with 2c = 50 mm, a/2c = 0.30 has a matching constraint with single edge-notched bend specimen with a/W = 0.5 and single edge-notched tensile specimen with a/W = 0.1. The steam turbine blade with 2c = 50 mm, a/2c = 0.35 has a matching constraint with single edge-notched bend specimen with a/W = 0.4, compact tension specimen with a/W = 0.3 and central-cracked tension specimen with a/W = 0.7. The steam turbine blade with a = 15 mm, a/2c = 0.30 has a matching constraint with compact tension specimen with a/W = 0.7 and single edge-notched tensile specimen with a/W = 0.5. The steam turbine blade with a = 15 mm, a/2c = 0.40 has a matching constraint with compact tension specimen with a/W = 0.4. The steam turbine blade with a = 15 mm, a/2c = 0.50 has a matching constraint with single edge-notched bend specimen with a/W = 0.5.
