We study the stability of magnetorheological elastomers (MREs) undergoing finite deformations in the presence of a magnetic field and derive a general condition for the onset of macroscopic instabilities. In particular, we focus on anisotropic MREs with magnetoactive particles that are aligned along a particular direction, forming chain-like structures. We idealize the microstructure of such an...

In this study, environmental stains were removed from maxillofacial elastomers by solvent extraction. Silastic 44210, an RTV silicone with proven color and physical property stability, was stained with lipstick, disclosing solution, and methylene blue. These stains were then removed by solvent extraction with each of four chemically dissimilar solvents, namely: toluene, benzene, 1,1,1-trichloro...

malignancies of the midface result in cosmetic deformities that make maxillofacial prosthesis as an integral part of the treatment plan. facial defects can be devastating in their impact on physical structure and function of the affected individual, leading to potentional compromises in quality of life. reconstruction of nasal defects is a challenge for the prosthodontist because of esthetic an...

New anisotropic silicone magnetically active elastomers were synthesized and investigated by microscopy spectroscopy. The record magnetostriction value in the obtained composites was determined dynamic force microscopy, their surface original wrinkled microstructure visualized. topography changing small external magnetic fields found. Mössbauer spectroscopy use allowed determining iron filler e...

As a relatively new material deployed in additive manufacturing (AM), silicone and its composites have the potential to realize tunable functionality heterogeneous, architected properties for number of applications requiring low modulus, elastic materials. Continuous fiber reinforced been developed AM achieve various complex structures that are lightweight with high mechanical properties. silic...
