When measuring the internal resistance of a battery cell using the AC method, an AC resistance meter specifically designed to measure low resistance levels (i.e., a battery tester) is used. AC resistance meters apply a constant-current AC signal to the battery. [pdf]
Thermal, thermo-mechanical and mechanical properties of four different commercially available polyetheretherketones (PEEK) based materials were investigated. PEEK matrix was either modified and/or r. [pdf]
Dynamic modulus (sometimes complex 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 materials. [pdf]

is studied using where an oscillatory force (stress) is applied to a material and the resulting displacement (strain) is measured. • In purely materials the stress and strain occur in , so that the response of one occurs simultaneously with the other.• In purely materials, there is a between stress and strain, where strain lags stress by a 90 degree ( ) phase lag.The remaining fundamental quantity is the tangent of the phase lag, (tan (delta)), often simply called "tan delta" and sometimes called the "loss tangent". The in-phase and out-of-phase components of the dynamic modulus are known as the storage modulus and loss modulus, respectively. [pdf]
