Diamond young's modulus
WebYoung’s modulus E = initial slope of σt −εt curve = initial slope of σn −εn curve. Yield stress σy is the nominal stress at the limit of elasticity in a tensile test. Tensile strength σts is the nominal stress at maximum load in a tensile test. Tensile ductility εf is the nominal plastic strain at failure in a tensile test. The ... WebThe elastic moduli for diamond, (a cubic material), are C11 =10.79±0.05×10 11 Nm −2, C12 =1.24±0.05×10 11 Nm −2 and C44 =5.78±0.05×10 11 Nm −2. These high values reflect the great strength of diamond. The following values are obtained for diamond.
