Modulus of resilience equation
WebResilient Modulus Testing for Pavement Components - Sep 06 2024 "Resilient modulus indicates the stiffness of a soil under controlled confinement conditions and repeated loading. The test is intended to simulate the stress conditions that occur in the base and subgrade of a pavement system. Resilient modulus has been adopted by the U.S. federal Web2 nov. 2015 · Where modulus of elasticity is calculated, the object under the deforming force either gets lengthened or shortened. Where modulus of rigidity is calculated, one of the surfaces of the object becomes displaced with respect to another surface. Relative Size. For most materials, the modulus of elasticity is larger than the modulus of rigidity.
