TL;DR: In this article, the authors investigated the sensitivity of post-buckled structures to dynamic state transitions in a more realistic scenario of combined harmonic and stochastic loading and found that persistent periodic snap-through dynamics are rapidly disabled by additional noise excitation when the harmonic excitation contribution occurs at frequencies close to the linearized resonance.

TL;DR: In this article, a model of the poroelastic foam spring and the area density of the mass layer are modified to achieve a target natural frequency of the device while the foam itself provides adequate dissipation of energy as the mass dynamically compresses it at resonance.

TL;DR: In this paper, the applicability of a superposition approach by which a non-continuous distributed spring layer is homogenized into a 2D continuum is explored, which allows computation of the required elasticity parameters of the spring layer.

TL;DR: In this article, the potential to rationally design functionally graded elastomeric materials to yield prescribed mechanical properties is demonstrated, following computational and experimental studies of simplified unit cells and layers, the results inspire ways to exploit linear elastic network analogies to design built-up and functionally graded materials.

TL;DR: The analysis reveals that the primary inclusion characteristic tuned by such parameter changes is the dynamic stiffness of the inclusions, together with the dynamic mass and dynamic stiffness work to induce two tuned-mass-damper-like behaviors that lead to broadband vibration attenuation capabilities.
