Transverse strength (also called modulus of rupture or flexural strength) measures a rock's ability to resist failure under bending (transverse) loads. It is determined by the three-point or four-point bending test on a rectangular beam specimen. Transverse strength is typically lower than compressive strength and higher than tensile strength. It is important for assessing rock used as flooring, cladding, or bridge stone where bending stresses occur.
