The elastic modulus of an object is defined as the slope of its stress–strain curve in the elastic deformation region: A stiffer material will have a higher elastic modulus. A centrally arranged loading pin bends the specimen as the load increases. In mechanics, the flexural modulus or bending modulus is an intensive property that is computed as the ratio of stress to strain in flexural deformation. For this purpose, a standardized specimen is mounted on two supporting pins of a universal testing machine. or bending) under a stress that does not exceed the materials elastic range. JSTOR ( November 2010) ( Learn how and when to remove this template message)Īn elastic modulus (also known as modulus of elasticity) is the unit of measurement of an object's or substance's resistance to being deformed elastically (i.e., non-permanently) when a stress is applied to it. In such a bending test flexural strength, deflection at fracture and modulus of elasticity, for example, are determined. In the simplest terms, the modulus of elasticity (MOE) measures a woods.E is the Youngs modulus of the beam material (Pa) I is the area moment of. Unsourced material may be challenged and removed. Methods for finding the deflection: The deflection of the loaded beam can be. Please help improve this article by adding citations to reliable sources. The higher its value, the greater the stress required to produce a certain amount of elastic deformation, meaning that the material is stiffer and experiences less elastic deformation under a given stress. This article needs additional citations for verification. Stress-strain curve Before the first yield point, the material will have an elastic behavior, which means that it will go back to its initial state if we. The Elastic Modulus is a measure of a material’s resistance to elastic deformation.
