Available in PDF, EPUB and Kindle. Book excerpt: Dynamic responses of the MR Elastomers and MR gel have been studied care- fully by various research groups. However, to understand completely the dynamic response of the material, it is important to have a clear understanding of quasi-static response of the material. Thus, for the current work, we have studied quasi-static response of the MR gel. For current setup, 27 samples were prepared using Septon, plasticizer and magnetic particles and were tested for 3 rounds over 3 different magnetic fields under plane strain compression. The results from plane strain compression show linear increase in the load taken with the increase in concentration of magnetic particles in absence of any magnetic field. The response characteristics under uniform magnetic field showed a huge leap in the load taken for particular deflection. To study the quasistatic respose, the material is assumed to behave like an isotropic hyperelastic response. Field dependent Neo-Hookean and field dependent Valanis Landel models have been fit to the data, and it was found that simple 1-term field dependent Valanis Landel model with power law coefficient as four agrees well with the shear modulus obtained from experiments. The shear modulus of MAP from the Valanis Landel and Neo Hookean model was assumed to be linearly dependent on the concentration of magnetic particles and magnetic field, and this matched the experimental data well.

Book Synopsis DESIGN AND CHARACTERIZATION OF MAGNETIC FIELD ACTUATED MULTILAYERED POLYMERS. by : Rui Leng
Download or read book DESIGN AND CHARACTERIZATION OF MAGNETIC FIELD ACTUATED MULTILAYERED POLYMERS. written by Rui Leng and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates multi-field actuated smart materials for potential biomedical applications. Magneto-active elastomers (MAEs) consisting of magnetic particles and a two-part elastomer were first designed and tested for their degree of actuation as unimorphs. The study considered two types of magnetic particles, hard and soft. For hard magnetic particles, barium hexaferrite (BHF) microparticles were chosen based on their responsiveness to magnetic field and their hard magnetic properties. The permanent magnetic dipoles of BHF resulting in large remanent magnetization can be polarized by magnetic field into designed directions. For soft magnetic particles, iron oxide microparticles were chosen where application of magnetic field results in induced dipoles. The elastomer matrix for the MAEs was fabricated using a two-part polydimethylsiloxane (PDMS) base and curing agent. BHF-PDMS and iron oxide-PDMS were fabricated using conventional casting method, processed into unimorphs and actuated as proof of concept. A unimorph structure is a layered structure where a substrate material is deformed using an active material and designed for large bending deformation. Bending and folding actuation was elicited with BHF-PDMS thin films as the particle magnetic dipoles were poled in a uniform direction beforehand. The film then reacts to external magnetic field by aligning the dipole directions with the external magnetic field direction. Iron oxide-PDMS was also studied and actuated using external magnetic field. Other actuation configurations designed included gripping and flower blooming motions. Large bending actuation was achieved with both hard and soft MAEs, and the next step was to test for printability. Iron oxide-PDMS was chosen for the printability test and the material compositions was tuned by adjusting base to curing agent ratio and by the addition of thickening agent. The printability study considered parameters such as temperature and number of printed layers, and results showed that printable iron oxide-PDMS slurries were obtained with 5wt% fumed silica added. The matrix of the magneto-active polymer-based materials was also investigated by comparing PDMS with mechanically stiffer polyvinyl alcohol (PVA) in degree of actuation. In the last step, multi-field actuation was studied using both conventional casting and additive manufacturing (AM) methods. Shape memory polymers (SMPs) were chosen to act as the "active" substrate for their shape fixing and recovery abilities under different temperatures. Unimorph structures were again used to test actuation of MAE-SMP under both magnetic and thermal fields. A gripping configuration was designed and demonstrated using conventionally cast iron oxide-PDMS and SMPs. Printed iron oxide-SMP thin films were actuated to assess the impact of the functional gradient design, showing different degree of actuation with different compositions of materials. The outcome of this research aims at potential biomedical applications using smart materials to allow non-contact control with large actuations. Additive manufacturing will enable the facile fabrication of actuators using these multiple materials, and would allow more customized devices to be printed for ease of use, while adapting to each patient's unique condition and requirement.
Book Synopsis Soft Robotics by : Gareth J. Monkman
Download or read book Soft Robotics written by Gareth J. Monkman and published by Bentham Science Publishers. This book was released on 2022-04-08 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soft robotics is a subfield of robotics that encompasses the design and fabrication of robots with soft and compliant materials. Soft robots represent components like human prosthetics or biomimicking systems. Soft robotics relies on technically astute designs based on the correct choice of materials to enable a level of dexterity not possible with rigid components alone. The basic prime movers (actuators) and perception (sensors) require control systems capable of accommodating imprecise feedback data and often unpredictable reaction times. Mobility in such robots is more akin to entomological or marine systems than conventional guided vehicles. This reference is a guide to materials and systems used in soft robotics. If features 6 chapters contributed by robotics experts that review fundamental and applied topics that are important for understanding the requirements of soft robotics design projects and the physics of the polymers involved. Chapters are organized for easy reading and include references.

This book was released on 2013-06 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smart adaptive materials are an important class of materials which can be used in space deployable structures, morphing wings, and structural air vehicle components where remote actuation can improve fuel efficiency. Adaptive materials can undergo deformation when exposed to external stimuli such as electric fields, thermal gradients, radiation (IR, UV, etc.), chemical and electrochemical actuation, and magnetic field. Large strain, controlled and repetitive actuation are important characteristics of smart adaptive materials. Polymer nanocomposites can be tailored as shape memory polymers and actuators. Magnetic actuation of polymer nanocomposites using a range of iron, iron cobalt, and iron manganese nanoparticles is presented. The iron-based nanoparticles were synthesized using the soft template (1) and Sun's (2) methods. The nanoparticles shape and size were examined using TEM. The crystalline structure and domain size were evaluated using WAXS. Surface modifications of the nanoparticles were performed to improve dispersion, and were characterized with IR and TGA. TPU nanocomposites exhibited actuation for approximately 2wt% nanoparticle loading in an applied magnetic field. Large deformation and fast recovery were observed. These nanocomposites represent a promising potential for new generation of smart materials.
