摘要:

This paper deals with the determination of stresses around a circular hole in a cantilevered wedge of uniform thickness subjected to end loading, using electrical resistance strain gauges. The authors have previously reported a similar investigation on a 45 wedge. The results obtained are compared with the theoretical analysis for an infinite perforated wedge given by Ling and Hsu. The stress concentration factors are calculated on the basis of nominal stress in the wedge at the hole boundary (using the theory for calculating stresses in a wedge without a hole). A maximum stress concentration factor of 3–2 was indicated for an end vertical load; and a maximum factor of 2 6 was indicated for an end horizontal loa

摘要:

This paper describes a technique for measuring and calculating CTOD (crack tip opening displacement) arid the J‐integral with double clip gauge. CTOD (or δ) and the rotation factor (r), the relation between δ and J‐integral, as well as the R‐curves δ ‐ Δa and J. Δa are discussed. From the measurements with double clip gauge, one can calculate CTOD and J througout the entire loading process. The present technique seems to be a better approach than DD19, in which r is taken as a consta

摘要:

In this note an alternative technique for measuring curvature and twist is discussed. The method relies on measuring the line spacing in a single exposure reflected pattern. Use of this technique appears to be preferable in many applications.
