what is the difference between flexural modulus and flexural strength
Flexural strength is a measure of the tensile strength of concrete beams or slabs. Flexural strength identifies the amount of stress and force an unreinforced concrete slab, beam or other structure can withstand such that it resists any bending failures.
Flexural modulus is a measure of how a certain material reacts to weight and force. Flexural modulus is an important concept in engineering. The beams used in a tunnel design must be strong enough to support thousands of tons of concrete and dirt.
