RISNew and Improved Analytical Solutions for the Self-Folding Problem of Carbon Nanotubes
Publisher: American Society of Civil Engineers
Abstract: It has been observed experimentally and computationally that a carbon nanotube with a large aspect ratio can self-fold because of the van der Waals force between parts of the same carbon nanotube. The primary issue in the ...
Stress Fields in a Continuous Fiber Composite With a Variable Interphase Under Thermo-Mechanical Loadings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Stress fields in a continuous fiber composite with a variable interphase subjected to thermomechanical loadings are studied by using a four concentric circular cylinders model. An exact closed ...
Approximate Solutions for a Self-Folding Problem of Carbon Nanotubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper treats approximate solutions for a self-folding problem of carbon nanotubes. It has been observed in the molecular dynamics calculations (, Gao, and Huang, 2006, “ Self-Folding and ...
Reflection and Transmission by a Periodic Array of Coplanar Cracks: Normal and Oblique Incidence
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Scattering of in-plane elastic waves by a periodic array of coplanar cracks is investigated. This problem was first treated by Angel and Achenbach. The method of their solution was based on ...
Identification of the Location and Level of Damage in Multiple-Bolted-Joint Structures by PZT Actuator-Sensors
Publisher: American Society of Civil Engineers
Abstract: A piezoceramic (PZT) patch can be used simultaneously as an actuator and as a sensor for structural damage detection by utilizing its electromechanical coupling property. In this technique, a PZT actuator-sensor patch is ...
Thermal Stress in a Coated Short Fibre Composite
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When a coated short fibre composite is subjected to temperature change, thermal stresses in and around the coated fibres are induced due to the mismatch of thermal expansion coefficients of ...
Wind-Induced Vibration and Control of Trans-Tokyo Bay Crossing Bridge
Publisher: American Society of Civil Engineers
Abstract: The Trans-Tokyo Bay Highway Crossing, completed in 1997, is 11 km in total length and is a combined tunnel and multiple bridge route that includes a ten-span continuous steel box-girder bridge with a total length of 1,630 ...
Design Formulas for Damping of a Stay Cable with a Damper
Publisher: American Society of Civil Engineers
Abstract: The performance of a damper in controlling large-amplitude vibrations of a stay cable in a bridge is influenced by essential parameters such as the amount of sag and flexural rigidity of the cable, and the stiffness of the ...
Combined Damping Effect of Two Dampers on a Stay Cable
Publisher: American Society of Civil Engineers
Abstract: The combined effect of two dampers, either on the same end or opposite ends of a stay cable, is analytically studied in this paper. By considering small distances of the dampers from the anchorages, an asymptotic formula ...
Interaction of Nonconservative 1D Continuum and Moving MDOF Oscillator
Publisher: American Society of Civil Engineers
Abstract: This paper presents a method for computing the response of a 1D elastic continuum induced by a multi-degree-of-freedom (MDOF) oscillator traveling over it. The continuum and the oscillator are nonconservative systems with ...
