Dynamic Mechanical Response and Damage Mechanism of HTPB Propellant under Impact Loading. [PDF]

Materials (Basel), 2020
The dynamic mechanical behaviors of Hydroxyl-terminated polybutadiene (HTPB) propellant was studied by a split Hopkinson pressure bar apparatus (SHPB) at strain rates ranging from 103 to 104 s−1. The obtained stress–strain curves indicated that the mechanical features, such as ultimate stress and strain energy, were strongly dependent on the strain ...

Dynamic intracellular mechanical cues facilitate collective signaling responses [PDF]

iScience, 2021
Collective behavior emerges in diverse life machineries, e.g., the immune responses to dynamic stimulations. The essential questions that arise here are that whether and how cells in vivo collectively respond to stimulation frequencies higher than their intrinsic natural values, e.g., the acute inflammation conditions.

Dynamic mechanical response of polymer networks [PDF]

The Journal of Chemical Physics, 2000
The dynamic-mechanical response of flexible polymer networks is studied in the framework of the tube model, in the limit of small affine deformations, using the approach based on Rayleighian dissipation function. The dynamic complex modulus G*(ω) is calculated from the analysis of a network strand relaxation to the new equilibrium conformation around ...

Model identification and dynamic analysis of ship propulsion shaft lines [PDF]

Journal of Theoretical and Applied Vibration and Acoustics, 2015
Dynamic response analysis of mechanical structures is usually performed by adopting numerical/analytical models. Finite element (FE) modeling as a numerical approach plays an important role in dynamic response analysis of complex structures.

Dynamic mechanical response of foams for noise control [PDF]

AIP Conference Proceedings, 2016
In this work, the viscoelastic behavior of open cell polyurethane foams used in noise control applications is investigated through dynamic mechanical analysis in compression. Several levels of static strains superimposed on a small dynamic one were considered in order to assess the effect of material non-linearity on the mechanical response. Further, a
