full-thickness sample

Assessment of the mechanical properties of Russian K65 gas-line pipe is considered. The tensile strength and impact strength of small and large samples and the static flexure of full-thickness samples with fatigue cracks are determined by failure-mechanics methods. The cyclic crack resistance is also determined. The best methods are identified.

Figures 8 and 9 show the full-thickness specimen design for the CTOD tests

The Tkb test according to RMRS rules (Russian Maritime Register of Shipping et al. 2012) and BS 7448 (BS 7448-1:1991) is performed on a specially shaped full-thickness specimen; geometrical dimensions of the specimen are shown in Fig. 6.

Both tested steel plates, E500 and F500W, showed similar results. Tkb is a full-thickness test; therefore, similar E500 and F500W results are substantially different, and F500W performs significantly better, as it is 10 mm thicker.
Specimens after testing are shown in Fig. 7.

The percentage of ductile fracture was measured according to GOST 30456 97. Tkb tests results are shown in Table 10.

Base metal cold-resistant tests: Tkb test

Both tested steel plates, E500 and F500W, showed similar values: −40 °C for E500 and −38 °C for F500W. However, as Tkb is a full-thickness test; therefore, the similar E500 and F500W test results are indicating that the 35-mm-thick F500W performs significantly better than 25-mm E500 steel.
Base metal cold-resistant tests: CTOD test

CTOD full-thickness test results at −40 °C showed the superiority of the F500W steel plate made by QT method. RMRS rules set a required CTOD value for the tested steels in the range of at least 0.15–0.30 mm, depending on the importance of the structural element and the loading conditions.

  -> Thank you, Jack. A "full-thickness specimen" can be used interchangeably with "sample." Best regards and wishes of a great day, Jack.
