Natural stone test methods - determination of the dynamic modulus of elasticity by measuring the fundamental resonance frequency ; german version en 14146 : 2004 天然石料试验方法.弹性的动态模量测定
With changing the value of every parameter of the model , we can analyse the impact on the dynamic modulus of elasticity " of every parameter 然后,改变模型各参数的值,分析各参数对动态弹性模量的影响。
Comparing the dynamic modulus of elasticity of the model in each age with the corresponding values of the test data , we can verified the feasibility of the method 将求得的各龄期的动态弹性模量与相应的试验数据相比较,验证方法的可行性。
Dynamic modulus is the ratio of stress to strain under vibratory conditions (calculated from data obtained from either free or forced vibration tests, in shear, compression, or elongation). It is a property of viscoelastic materials.
