Impact Testing on Subsize specimen

Zain96 · May 26, 2024

Hi Engineers,

OD-9.625"
WT-0.472"
Max-Yield Strength-95000PSI
Grade-L80
Specimen size for impact test- 10x7.5mm
Minimum Absorbed energy-?

As i have the above item, I would like more information about the impact testing that is being done on casings as per API 5CT 10th edition.
How do i calculate the minimum absorbed energy for subsize specimen-10x7.5, having reduction factor of 0.8

Would anyone kindly assist on this.

Derive the minimum required absorbed energy for a full size 10 mm test piece using 5CT, 7.5.2, and Table 10. Having derived that value, multiply it by 0.8. This assumes that the end user has not specified more onerous requirements like IOGP S-735, SL-A, for example.
