Thermomechanics of nano-filled elastomers
The incorporation of nanoparticles into engineering thermoplastic elastomers affords engineers an opportunity to formulate flexible, tough and multifunctional polymer nanocomposites that potentially rival the most advanced materials in nature. Development of these materials is difficult since …

Thermomechanics of helical strands and helical-fiber-reinforced rods
Helical strands, or helically wound cables, are made of layers of individual wires wrapped around a common central axis. They are seen in ropes and power transmission cables. Similar structures are also present in biological tissues in the form of helical fiber reinforced composites. Regardless of …

On the thermomechanics of localizing pseudoelastic transformations in NiTi materials and structures
Nearly equiatomic NiTi alloys undergo reversible solid-state transformations around room temperature, which are activated by the application of stress or by modest temperature changes. The forward transformation causes about 6% strain and the release of about 12 kJ/kg of latent heat; both are …

Experimental and Novel Analytic Results for Couplings in Ordered Submicroscopic Systems: from Optomechanics to Thermomechanics
Theoretical modelling of challenging multiscale problems arising in complex (and sometimes bioinspired) solids are presented. Such activities are supported by analytical, numerical and experimental studies. For instance, this is the case for studying the response of hierarchical and …

The Thermomechanical Response of Composite Energetic Materials Under High- and Low-frequency Mechanical Excitations
… of detectable vapors. In this work, the thermomechanics of plastic-bonded explosives, propellants, and surrogates thereof are investigated due to their widespread adoption in improvised explosive devices. These classes of material consist of energetic crystals held within an inert plastic …

Peridynamics For The Solution Of Multiphysics Problems
… field problems concerning plastic deformations, thermomechanics, hygrothermomechanics, hydraulic fracturing, thermal cracking of fuel pellet and electromigration are constructed. Their comparisons with the finite element predictions establish the validity of the PD field equations for coupled …

Renormalization analysis of continuum models on fractal domains
… on the recently begun extension of continuum thermomechanics to fractal media which are specified by a fractional mass scaling law of the resolution length scale R. The focus is on pre-fractal media (i.e., those with lower and upper cut-offs) through renormalization analysis into continuum …

An exploration of shape memory polymers and (nano) composites for packaging applications.
… networks, class I SMP, with tailorable thermomechanics were investigated. Tertiary butylacrylate (tBA) and polyethylene glycol dimethacrylate (PEGDMA) were copolymerized to create networks with adjustable glass transition temperatures (Tg) and rubbery modulus values ranging from -18 to …
