Stress–strain behavior of thermoplastic polyurethanes
Abstract The large strain nonlinear stress–strain behavior of thermoplastic polyurethanes (TPUs) exhibits strong hysteresis, rate dependence and softening. Thermoplastic polyurethanes are copolymersExpand
Changes in the structure-function relationship of elastin and its impact on the proximal pulmonary arterial mechanics of hypertensive calves.
Extracellular matrix remodeling has been proposed as one mechanism by which proximal pulmonary arteries stiffen during pulmonary arterial hypertension (PAH). Although some attention has been paid toExpand
Active materials by four-dimension printing
We advance a paradigm of printed active composite materials realized by directly printing glassy shape memory polymer fibers in an elastomeric matrix. We imbue the active composites with intelligenceExpand
A thermoviscoelastic model for amorphous shape memory polymers: Incorporating structural and stress relaxation
Abstract A thermoviscoelastic constitutive model is developed for amorphous shape memory polymers (SMP) based on the hypothesis that structural and stress relaxation are the primary molecularExpand
Finite deformation thermo-mechanical behavior of thermally induced shape memory polymers
Abstract Shape memory polymers (SMPs) are polymers that can demonstrate programmable shape memory effects. Typically, an SMP is pre-deformed from an initial shape to a deformed shape by applying aExpand
Constitutive model for stretch-induced softening of the stress?stretch behavior of elastomeric materials
Abstract Elastomeric materials experience stretch-induced softening as evidenced by a pre-stretched material exhibiting a significantly more compliant response than that of the virgin material. InExpand
Nanoscale morphology and indentation of individual nacre tablets from the gastropod mollusc Trochus niloticus
The inner nacreous layer of gastropod mollusc Trochus niloticus is composed of ∼95 wt% planar arrays of polygonal aragonite-based tablets (∼8 μm wide, ∼0.9 μm thick, stacked ∼40 nm apart) and ∼5 wt%Expand
Recent progress in shape memory polymer: New behavior, enabling materials, and mechanistic understanding
Shape memory polymers (SMPs), as a class of programmable stimuli-responsive shape changing polymers, are attracting increasing attention from the standpoint of both fundamental research andExpand
Durometer Hardness and the Stress-Strain Behavior of Elastomeric Materials
Abstract The Durometer hardness test is one of the most commonly used measurements to qualitatively assess and compare the mechanical behavior of elastomeric and elastomeric-like materials. ThisExpand
A 3D finite deformation constitutive model for amorphous shape memory polymers: A multi-branch modeling approach for nonequilibrium relaxation processes
Abstract Shape memory polymers (SMPs) are materials that can recover a large pre-deformed shape in response to environmental stimuli. For a thermally activated amorphous SMP, the pre-deformation andExpand
