Practical causal hysteretic damping

Earthquake Engineering & Structural Dynamics, 2006
AbstractA number of experiments indicate that the internal damping corresponding to the energy dissipation of many materials is essentially frequency independent. Accordingly, an analysis model that can express such characteristics (called a hysteretic damping model) in the time domain is needed.

Hysteretic damping and causality

Acoustical Physics, 2013
It is proven that linear oscillatory systems with hysteretic damping in the form of complex stiffness and/or complex elastic moduli satisfy the causality principle: the response of such a system to an arbitrary external force cannot appear earlier than the onset of the force. The proof, based on a rigorous solution to the problem of forced oscillations,

Insuring causality of frequency-response functions with hysteretic damping

The Journal of the Acoustical Society of America, 2001
When calculating the temporal response h(t) of a system responding linearly to an external impulsive force applied at t=0, the availability of personal computers that calculate Fourier transforms may make it convenient to first calculate the frequency-response function H(ω) of the system and then obtain h(t) as the inverse Fourier transform of H(ω ...

Response analysis of soil deposit considering both frequency and strain amplitude dependencies using nonlinear causal hysteretic damping model

Earthquakes and Structures, 2013
It is well known that the properties of the soil deposits, especially the damping, depend on both frequency and strain amplitude. Therefore it is important to consider both dependencies to calculate the soil response against earthquakes in order to estimate input motions to buildings.
