RISCould Shock Tests Adequately Mimic Drop Test Conditions?
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Drop tests are often substituted in qualification or life testing of microelectronic and optoelectronic products by shock tests. The existing (e.g., Telcordia) qualification specifications require ...
Feature-Based Optimization of Beam Structures Represented by Polygonal Meshes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a new shape optimization approach, feature-based optimization of beam structures, is proposed to provide an efficient optimization solution of beam components in complex mechanical ...
Integrity Assessment of Pressure Components With Local Hot Spots
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Local hot spots can occur in some pressure vessels and piping systems used in industrial processes. The hot spots could be a result of, for instance, localized loss of refractory lining on ...
A Methodology for Predicting the Variance of Fatigue Life Incorporating the Effects of Manufacturing Processes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is well known that there is a large variance of fatigue life associated with the data of fatigue tests under nominally identical conditions. Understanding and controlling this variance are ...
Process Parameters and Residual Stresses in Cylindrical Grinding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper presents an experimental study on the relationship between process parameters and residual stresses in cylindrical grinding. In particular, the influence of the depth of cut (a) and ...
Chatter Instability in Milling Systems with Flexible Rotating Spindles—A New Theoretical Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The stability characteristics of a milling system are investigated in this paper. A model is developed that includes the gyroscopic effects of the rotating spindle and on the basis of this ...
Managing Complex Vehicle System Simulation Models for Automotive System Development
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A Model Management System (MMS) for vehicle dynamic system modeling is described, including lessons learned from a pilot implementation at Ford Motor Company. For complex vehicle systems, early ...
Mathematical Modeling of Ultra-High-Pressure Waterjet Peening
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Waterjet peening is a recent promising method in surface treatment. It has the potential to induce compressive residual stresses that benefit the fatigue life of materials similar to the ...
A Finite Element Study of Elasto-Plastic Hemispherical Contact Against a Rigid Flat
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work presents a finite element study of elasto-plastic hemispherical contact. The results are normalized such that they are valid for macro contacts (e.g., rolling element bearings) and ...
Automatic CAD Model Reconstruction from Multiple Point Clouds for Reverse Engineering
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a systematic scheme is proposed and novel technologies are developed to automatically reconstruct a CAD model from a set of point clouds scanned from the boundary surface of ...
