Structure-property relationships in polymeric materials via advanced rheological and neutron scattering techniques
… exhibit maximum elasticity around the maximum strain. With the analysis, we observe that the cages are recoverably strained by a nearly constant amount of 5%, even with the total strain amplitude of 420%. To understand how microscopic rearrangements manifest in time-dependent macroscopic …

A new mechanical characterization method for thin film microactuators and its application to NiTiCu shape memory alloy
… loading method for freestanding SMA thin films, strain resolution of 30 [mu]E and stress resolution of 2.5 MPa were achieved. This new testing method is presented against previous SMA characterization methods for purposes of comparison. Four mm long, 2 [mu]m thick NiTiCu ligaments suspended …

The Characterization and Control of Shape Memory Alloy Cables for Reinforcement of Engineered Cementitious Composite Beams
… many attractive features, such as large recoverable strain, large load bearing capacity, among others. To understand the characteristics of the Nitinol cable, a series of experiments were conducted to derive its key parameters, which was not provided by the manufacturer. A sliding mode …

Shape Memory Alloys for small scale actuation
… (SMAs), materials that can undergo a fully recoverable strain change due to a thermal cycle, and which can be produced in a form that is superelastic are only utilized limitedly. In this thesis, I investigated the relationship between the material properties of shape memory alloy micro-wires …

Large contraction conducting polymer molecular actuators
… strength (10 - 40 MPa) but moderate active strains (2 %). Active strains of 20 %, which human skeletal muscle is capable of, are desirable for applications in life-like robotics, artificial prostheses or medical devices. This thesis focuses on two approaches to create large contraction in …

Tensile creep of silicon carbide whisker-reinforced alumina composites
… 20 and 30% whiskers showed significant anelastic strain recovery (∼0.001) following tensile creep, which is consistent with earlier reports that involved bending creep tests. The whisker bending effect was studied by measuring the peak width of (111) SiC planes (perpendicular to the whisker axis) …
