Microstructures havea significant effect on theperformanceof critical components innumerous aerospacemetallic material applications. Examples include panels in airframes that are exposed to high temperatures and sensors used for vibration tuning. This paper addresses the techniques to optimize the microstructure design for polycrystalline metals. The microstructure is quantified with the orient...
Submitted for the MAR14 Meeting of The American Physical Society Instability and Wave Propagation in Structured 3D Composites NARGES KAYNIA, NICHOLAS X. FANG, MARY C. BOYCE, Massachusetts Inst of Tech MIT — Many structured composites found in nature possess undulating and wrinkled interfacial layers that regulate mechanical, chemical, acoustic, adhesive, thermal, electrical and optical function...
Folding 2D sheets into desired 3D structures is a promising fabrication technique that can find a wide range of applications. Compressive buckling provides an attractive strategy to actuate the folding and can be applied to a broad range of materials. Here a new and simple method is reported to achieve controlled compressive buckling, which is actuated by a heat shrinkable polymer sheet. The bu...
Buckle-initiation techniques, such as sleepers, are usually installed to trigger lateral buckling at pre-designated locations release the axial compressive forces induced by thermal loading. Taking nonlinear pipe–soil interaction model into account, a mathematical is proposed investigate of subsea pipelines triggered sleeper. The numerical solution validated comparing with solutions in literatu...
Differential growth of thin elastic bodies furnishes a surprisingly simple explanation of the complex and intriguing shapes of many biological systems, such as plant leaves and organs. Similarly, inelastic strains induced by thermal effects or active materials in layered plates are extensively used to control the curvature of thin engineering structures. Such behaviour inspires us to distinguis...
Two dimensional crystalline membranes in isotropic embedding space exhibit a flat phase with anomalous elasticity, relevant e.g., for graphene. Here we study their thermal fluctuations the absence of exact rotational invariance space. An example is provided by membrane an orientational field, tuned to critical buckling point application in-plane stresses. Through detailed analysis, show that tr...
