In NC titanium, the volumetric share of grain boundaries is an order of magnitude lower than that in Ni–P, where the decrease in the Young's modulus is substantial. Elastic modulus is a key parameter employed to estimate the deformation of structures and structural members and is typically expressed in terms of the compressive strength [, , , ]. De elasticiteitsmodulus (of ook Youngs modulus, naar de Engelse natuurkundige, dokter en egyptoloog Thomas Young), is een materiaaleigenschap die een maat is voor de stijfheid of starheid van een materiaal en die ten dele de rek van het materiaal onder een trekbelasting bepaalt en de compressie onder een drukkracht.. The Modulus of Elasticity Provided that the elastic limit is not exceeded, an elastic deformation (strain) is directly proportional to the magnitude of the applied force per unit area (stress). Units of elastic modulus are followings: In SI unit MPa or N/mm 2 or KN/m 2. Hence this may be not the only factor which influence on the elastic modulus value. An isotropic elastic modulus was calculated from the unloading curve with an assumed Poisson ratio of 0.3, while hardness was defined as the maximal force divided by the corresponding contact area. Elastic modulus is a fundamental parameter in designing concrete structures. Modulus of Elasticity of Concrete.
