摘要：

Experimental determination of compliance over the approximate range of a/W from 0.3 to 0.7 has been undertaken for compact tension and cantilever beam test specimens. The test data have been processed using a recently proposed analytical procedure, and the results for compliance functions have been compared with some standard results available in the literature. The agreement between the experimental results and the proposed compliance functions equation for compact tension geometry of ASTM E399 is excellent. However, for the cantilever beam specimen, it is demonstrated that the usual Srawley and Brown equation for pure bending may underestimate the compliance function by as much as 14%. © 1979.
