How to calculate biaxial flexure
The flexural strength would be the same as the tensile strength if the material were homogeneous. In fact, most materials have small or large defects in them which act to concentrate the stresses locally, effectively causing a localized weakness. When a material is bent only the extreme fibers are at the largest stress so, if those fibers are free from defects, the flexural strength will be controlled by the strength of those intact 'fibers'. However, if the same material was subjected t… Web1 jan. 1992 · biaxial flexure testing analysis The NIKE3D finite element program developed at Lawrence Livermore National Laboratory was used to calculate the stresses in the specimen as it is loaded in the ...
