This paper examines the effects of normal and lateral high-speed impacts on carbon fiber-reinforced polymer laminates. Experimental tests were conducted at varying velocities (120–200 m/s), and the differing damage modes between normal and lateral impacts were analyzed. Dynamic finite element analysis was performed to simulate the damage process using the finite element software ABAQUS. The simulation...
A suite of codes, named Microwave Tube Simulator Suite (MTSS), will be presented. MTSS is a full-featured tightly integrated software package for vacuum electron devices analysis and design. It includes a commercial grade user interface and three physics simulators. The Electron Optics Simulator (EOS) is a finite-element two dimensional and three dimensional electrostatic steady-state beam trajectory...
Osteoporotic patients occur frequently fragile fractures, and femoral fractures are the common traumatic injuries in the elderly. Although wires are often used through trials-and-errors for unstable femoral proximal fractures with DHS fixation clinically, there is no efficacy wire fixation technique available due to the lack of biomechanical study. FEM is applied to analyze the stress and strain distribution...
Summary form only given. Microwave Tube Simulator Suite (MTSS) is a full-featured, tightly integrated software package for microwave tube analysis and design. It includes a friendly user interface module and five physics simulators. Microwave Tube Design Environment (MTDE) is the user interface module, which provides a powerful solid modeling front-end and graphical and computational post-processing...
The assembly of a single carbon nanocoil on the tip of an atomic force microscope probe has been demonstrated by utilizing dielectrophoresis in an isopropyl alcohol solution. The nanocoil adheres to the probe tip where the maximum electrical field exists. Its orientation due to the relative position between the probe tip and the dielectrophoresis electrode has been investigated. The capillary effect...
This paper deals with the finite element analysis (FEA) of two 5-DOF reconfigurable hybrid robots, the Tricept and the TriVariant, by means of ANSYS parametric design language (APDL). The research interests are focused on: (1) precise FEA formulation of different types of joints by setting of contact elements, and (2) the development of an effective modeling strategy for the rapid stiffness and natural...
