top modulus of elasticity silicon carbide

Measurement and analysis of elastic and anelastic

Measurements of dynamic Young''s modulus, E, and damping as a function of temperature, T, were made for alumina and silicon carbide. The Young''s modulus data were compared with some from the literature, and analysed in terms of a theoretical framework relating the Debye temperature, θD, with the elastic constants. For both materials this analysis yielded a ratio T0/θD which was near 0.4


Moreover, fused silica has only a low modulus of elasticity (elastic modulus) of 50,000 to 80,000 MPa. As a result, the thermally induced stresses in this material are low. The use of fused silica results, furthermore, in an improvement in the product quality, since no metals (e.g., nickel) are released during the deposition, as may be the case

Young''s Modulus: Definition, Measurement, and Typical

Young’s modulus may be thought of as a substance’s resistance to elastic deformity; the stiffer the material, the higher its elastic modulus. For the majority of metals, this modulus ranges from 45 GPa (gigapascals) in the case of magnesium to 407 GPa for tungsten.
