Resource type: Equation
Description: The End Notch Flexure (ENF) test is used to determine the mode II fracture energy of a composite material.

TeX format: {G_{Iic} = \frac{9a^2P^2}{16EB^2h^3}}

GIic {G_{Iic}} = mode II fracture energy (J.m-2) {J.m^{-2}}
a {a} = distance from end support to crack tip (m) {m}
P {P} = force (N) {N}
E {E} = Young's modulus (Pa) {Pa}
B {B} = sample width (m) {m}
2h {2h} = sample thickness (m) {m}
