WebDynamic mechanical analysis, otherwise known as DMA, is a technique such that a small deformation is applied to a sample in a cyclic manner. This allows the material’s response to stress, temperature, frequency and other parameters to be studied. The term is also used to refer to the analyzer that performs the test.

WebSkeletal muscles respond to a single electric shock of sufficient magnitude by rapid, intense contractions called phasic contractions. If the ends of a frog sartorius muscle (at 0 °C) are fixed to prevent shortening, the tension increases for about 200 milliseconds and then begins to decrease, at first rather rapidly and then more slowly. More happens during this … WebMechanical resonance is the tendency of a mechanical system to respond at greater amplitude when the frequency of its oscillations matches the system's natural frequency of vibration (its resonance frequency or resonant frequency) closer than it does other frequencies.

The company produces mechanical parts for airplane … WebMost mechanical systems have resonant frequencies in the hundreds of hertz or lower. If the resonant frequency is significant, it will usually produce an audible sound which can be perceived by the listener. A similar but more precise tool, the Bode plot, analyzes the gain and phase of the response, and generates a plot in the frequency domain.

WebThe frequency response function (FRF) is defined as the ratio between response and excitation as function of excitation frequency. For unit excitation amplitude, FRF is given by Eq. (5.151). The response is a complex number, hence FRF will also be a complex number defined by magnitude FRF and phase θ.
