Abstract

The ASTM Split-D test method has been used to obtain the tensile strength as well as the modulus of filament wound composites. It is used extensively due to its relatively straightforward test configuration compared to the hydro-burst method. However, the Split-D method does have a drawback. There is a known stress concentration in the composite ring specimen at the location of the split, which affects a lower ultimate stress and strain. In this work, the researchers have applied digital image correlation to measure the full field strains near the fixture edge along with strain gage measurements for 508 mm diameter T1000 carbon fiber composite specimens. Details of the test setup and finite element analytical model are described in the paper. Also, results are compared to hydro-burst experiments that were conducted on specimens cut from the same parent rings as the Split-D specimens.
