Fatigue strength test of casting material GS-20Mn5V
The Small-sample up and down fatigue test method was used to test the fatigue limit of casting GS-20Mn5V which is the most popular casting material in civil engineering. The symmetric tension-compression fatigue test was on the high frequency fatigue tester. Ten useful test values were obtained through twelve tests with standard specimens. The mean value of fatigue limit of GS-20Mn5V is 202.8MPa after a statistic of the test results. The test provides the available data for engineering application.

Engineering critical analyses to BS 7910 — the UK guide on methods for assessing the acceptability of flaws in metallic structures
The well-known fitness-for-purpose (FFP) standard PD 6493:1991 has been revised and is now published as the British Standards Guide BS 7910. The revisions include modifications to the fracture and fatigue assessment clauses and many additional appendices have been added to complete the guidance provided. The PD 6539:1994 procedures for high temperature assessment have been incorporated as clause 9. This paper presents a brief historical review of the UK developments of FFP methods and outlines the modifications to BS 7910. In addition, the new BS 7910 fracture assessment clause is validated using a series of wide plate tests.
