3 terminology and units of measurement

JJF 1001-2011, JJF 1156-2006, GB/T 50082-2009 and DL/T 5150-2001 in the community And given the following terms and definitions apply to this specification. Dynamic elastic modulus dynamicelasticmodulus By the power law principle, according to elastic wave propagation velocity in the object of the modulus of elasticity measured. Note. The dynamic modulus of elasticity can be divided into horizontal longitudinal dynamic elastic modulus and dynamic elastic modulus. Lateral dynamic elastic modulus by the equation (1) is calculated. Edt = kdtWL3f2/a4 (1) Where. Edt --- lateral dynamic elastic modulus, GPa; a --- test block square cross-section side length, mm; L --- test block length, mm; W --- quality test block, kg; f --- specimen resonance frequency of the lateral vibration, Hz; kdt --- lateral dynamic elastic modulus calculation constants, kdt = 13.244 × 10-7. Longitudinal dynamic elastic modulus by the equation (2) is calculated. Edl = kdlWLf2/a2 (2) Where. Edl --- longitudinal dynamic elastic modulus, GPa; a --- test block square cross-section side length, mm; L --- test block length, mm; ......
