Abstract
Wide plate tension tests are commonly executed to investigate the integrity of defective welds under a uniaxial load. The specimen can be flat or curved, depending on the geometry from which it has been extracted (plate or pipe). Despite its usefulness, the design of the (curved) wide plate test is still not standardized up-to-date. This paper compares two specimen designs with a different length-to-width ratio through finite element analysis, using a design-of-experiments approach to account for different influential factors. The results reveal significant differences between the interpretation of tests with net section collapse and gross section collapse, promoted by weld strength overmatch. Further, both investigated designs tend to provide similar estimates of failure mode, strain capacity and crack driving force. Hence, the shorter specimen is considered an acceptable alternative to the slightly more representative longer specimen.
