A Three-Dimensional Thermomechanical Model of Contact Between Non-Conforming Rough Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A necessary step in understanding failure problems of tribological elements is to investigate the contact performance of rough surfaces subjected to frictional heating. It is essential that the ...
Studying Contact Stress Fields Caused by Surface Tractions With a Discrete Convolution and Fast Fourier Transform Algorithm
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The knowledge of contact stresses is critical to the design of a tribological element. It is necessary to keep improving contact models and develop efficient numerical methods for contact ...
Elastic Fields due to Eigenstrains in a Half-Space
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Engineering components inevitably encounter various eigenstrains, such as thermal expansion strains, residual strains, and plastic strains. In this paper, a set of formulas for the analytical ...
Transient Thermoelastic Stress Fields in a Half-Space
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computing the thermoelastic stress field of a material subjected to frictional heating is essential for component failure prevention and life prediction. However, the analysis for three-dimensional ...
Thermoelastic Asperity Contacts, Frictional Shear, and Parameter Correlations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A thermoelastic asperity contact model has been developed for two-dimensional problems. This model takes into account a steady-state heat transfer and the asperity distortion due to thermoelastic ...
The Diagnosis about Spatiotemporal Characteristics and Driving Factors of Flash Drought and Its Prediction over Typical Humid and Semiarid Basins in China
Publisher: American Meteorological Society
Human-Related Uncertainty Analysis for Automation-Enabled Façade Visual Inspection: A Delphi Study
Publisher: ASCE
Abstract: Given that traditional façade visual inspection entails laborious, dangerous, and inefficient manual work, automation-enabled façade visual inspection has become a prevailing trend in both academia and industry. However, ...
Spacecraft Close Proximity to Noncooperative Target Based on Pseudospectral Convex Method
Publisher: ASCE
Abstract: This paper proposes a trajectory-optimization problem for spacecraft close proximity to a noncooperative target, aiming at the generation of a six-degree-of-freedom (DOF) trajectory with the fuel-optimal objective value ...
Searching for Robust Minimal-Order Compensators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method of designing a family of robust compensators for a single-input/single-output linear system is presented. Each compensator’s transfer function is found by using a genetic-algorithm search ...
