Asymmetric Bifurcation of Initially Curved Nanobeam
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we investigate the asymmetric bifurcation behavior of an initially curved nanobeam accounting for Lorentz and electrostatic forces. The beam model was developed in the framework of Euler–Bernoulli beam ...
Effective Mitigation of Shock Loads in Embedded Electronic Packaging Using Bilayered Potting Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Shock loads which are characterized by high intensity, short duration, and vibration at varied frequencies can lead to the failure of embedded electronics typically used to operate/control numerous devices. Failure of ...
Finite Element Modeling of Shot Peening Residual Stress Relaxation in Turbine Disk Assemblies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Surface enhancement techniques such as shot peening are extensively used to increase the fatigue life of components in gas turbine engines. Due to the combined thermomechanical nature of the loading encountered within an ...
Realistic Finite Element Simulations of Arc Height Development in Shot Peened Almen Strips
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is the objective of this study to conduct realistic simulations of the archeight development in shotpeened Almen strips using the finite element (FE) method. Unlike our earlier work which is devoted to relaxation of ...
Containment and Arrest of Blade Shedding in Gas Turbine Engines Using Novel Dual-Ring Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we examine the energy absorption and containment capabilities of a newly proposed dual-ring design accounting for interactions between a released blade and fully bladed fan disk using three-dimensional finite ...
Shear Lag Model for Regularly Staggered Short Fuzzy Fiber Reinforced Composite
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this article, we investigate the stress transfer characteristics of a novel hybrid hierarchical nanocomposite in which the regularly staggered short fuzzy fibers are interlaced in the polymer matrix. The advanced fiber ...
