RISProfile Rolling of Gears: A Boundary Element Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Profile rolling processes such as those for gears play a very important role in everyday manufacturing. It is demonstrated here that the boundary element method (BEM) can be used to analyze, ...
A Generalized Finite Element Analysis of Sheet Metal Forming With an Elastic-Viscoplastic Material Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A finite element analysis for elastic-viscoplastic problems in the presence of large strains is presented in this paper. The formulation is capable of using any of a class of combined ...
Real-Time Identification and Control of Springback in Sheet Metal Forming
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sheet metal forming processes are prone to variations in material and process parameters. In an unmanned manufacturing cell, all the control functions must be automated and real-time measurement, ...
A Boundary Element Analysis of Metal Extrusion Processes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The subject of this paper is an analysis of metal extrusion processes by the boundary element method (BEM). It is demonstrated here that the BEM can be used to analyze, efficiently and ...
An Analysis of Large Strain Viscoplasticity Problems Including the Effects of Induced Material Anisotropy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper examines the modeling of large shearing of solids that exhibit induced anisotropy during inelastic deformation. The “traditional” approach uses integration of material rates of certain ...
Interactions Among General Systems of Cracks and Anticracks: An Integral Equation Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cracks and rigid line inclusions, or anticracks, are commonly observed in many engineering materials, such as ceramics, intermetallics, etc. Interactions among these cracks and anticracks can ...
The Normal Approach, Contact, and Rebound of Lubricated Cylinders
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An algorithm has been developed to simulate the normal approach, contact, and rebound of lubricated cylinders. The detailed interaction between the lubricated cylinders is predicted, thus providing ...
Thermal Stresses in Layered Electronic Assemblies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermal stresses in layered electronic assemblies are one of the causes of the mechanical failure of electronic packages. A simple but accurate method of estimating these thermal stresses is ...
Dynamic Indentation Hardness and Rate Sensitivity in Metals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental technique for determining the dynamic indentation hardness of materials is described. Unlike the traditional static hardness measurements, the dynamic hardness measurements can capture ...
A Micromechanical Study of High Temperature Ti-Al Powder Compaction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Process induced micro-scale evolutions can greatly influence the strength and resilience of a high temperature ceramic and intermetallic component. A micromechanical study, based on a unit cell ...
