Storage modulus loss factor

DMA frequency sweep measurement of (A) storage modulus, (B) loss

The storage modulus, loss modulus and loss factor as a function of frequency are plotted in Fig. 8. The dynamic moduli (both E 0 & E 00 ) grows steeply with an increase in the frequency.

Dynamic modulus

Viscoelasticity is studied using dynamic mechanical analysis where an oscillatory force (stress) is applied to a material and the resulting displacement (strain) is measured. • In purely elastic materials the stress and strain occur in phase, so that the response of one occurs simultaneously with the other.• In purely viscous materials, there is a phase difference between stress and strain, where strain lags stress by a 90 degree ( radian) phase lag.

loss modulus複數模量的虛數部分。在黏彈性材料的力學性能測量中是一個重要參數。損耗模量愈小,表明材料的阻尼損耗因數也小,材料就愈接近理想彈性材料。模量中應力與變形異步的組

Introduction to Dynamic Mechanical Analysis and its Application

The ratio of the loss modulus to the storage modulus is defined as the damping factor or loss factor and denoted as tan δ. Tan δ indicates the relative degree of energy dissipation or
