The bending strength or flexural strength of a material is defined as its ability to resist deformation under load. During a bending test described in ASTM D790 the maximum achieved flexural stress value is noted as flexural strength. For materials that deform significantly but do not break the load at yield typically measured at 5 deformation/strain of the outer surface is reported as the

bending strength is about one and the optimum ratio for bending stiffness is about two. The theoretical curve which fits the experimental data fairly well shows that at core-to-face ratios greater than the optimum the increase in panel weight is relatively small. For example a 100 increase in weight ratio results in a 6 increase in panel
