The Young’s Modulus of Silicon Nitride Ceramics

9/8/2018· The Young’s modulus (E), or the modulus of elasticity, of a material determines the level of applied force required before it bends or breaks. It describes the constant ratio of tensile stress ( σ ) to tensile strain ( ε ) within the elastic limits of materials for both tension and compressive forces.

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

Young’s modulus is measured via the stress-strain curve, using the parameters of tensile strength, yield strength, per cent elongation, and reduction of area. The values of Young’s modulus for ceramics are roughly the same as for metals but are lower for polymers .
