Question

state the relation between flexural strength thickness of tile​

Answer 1

Answer:

When a material is tested in flexure, i.e. under bending; tensile stresses are produced on the top layers; zero stress at neutral axis and compressive stresses in layers below the neutral axis. In isotropic materials, when the material fails, the corresponding load is taken for calculation of flexural strength. Since the isotropic material fails in tensile portion; the strength is nothing but its tensile strength. Hence when tested using tensile mode on a UTM;; we designate it as tensile strength and when tested on flexural loading set-up, we call it as flexural strength. Ideally both should be same. In fact for ceramic materials; tensile strength is obtained using 3 point bending set-up because tensile specimens for ceramic materials cannot be prepared. Only difference is if any defect is present in the specimen; irrespective of its location; it affects tensile strength in the same manner because uifom tensile stresses are produced across the whole cross section. In bending situation however; defects will affect the strength differently depending upon their location. A defect nearer top or bottom surface will have significant effect as compared to the same type of defect located nearer or on the neutral axis. Hence the strength in two modes of testing may differ...
