1. An apparatus for determining at least one of a bending strength of a substrate or a peel strength of a joint between the substrate and a structure, the apparatus comprising:
a fixture configured to support the structure, wherein the substrate is joined to the structure;
a plurality of support beams, each support beam defined with a rolling support at a free end, wherein at least one of the plurality of support beams is provided on either side of the fixture for supporting the substrate; and
a plurality of load applying members configured to apply load onto a surface of the substrate outboard of the support beams such that the substrate deforms relative to the plurality of support beams, the applied load used to determine at least one of the bending strength of the substrate and peel strength of the joint between the substrate and the structure.
