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 …
