Design of a (mini) wide plate specimen for strain-based weld integrity assessment [PDF]
, 2011 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).
