RISFull-Scale Testing of Lateral Pressures in an Expansive Clay upon Infiltration
Publisher: American Society of Civil Engineers
Abstract: Full-scale testing of lateral pressures in expansive clay under various saturation conditions is crucial to better understand the behavior of these soils and predict potential damage to structures. However, due to their ...
A New Saturation-Based Framework for Compaction Quality Control
Publisher: ASCE
Abstract: Field compaction control is arguably the most common yet critical quality control procedure in geotechnical engineering. Since the early 1930s, the systematic process for performing quality control of compacted soils has ...
Impacts of Wildfires on Geotechnical Properties of Soils
Publisher: American Society of Civil Engineers
Abstract: Abstract Recorded data indicate an increasing trend of wildfires in several regions of the
United States and globally. The primary objective of this study is to examine the
changes in the geotechnical properties of ...
Impact of Toe Resistance in Reinforced Masonry Block Walls: Design Dilemma
Publisher: American Society of Civil Engineers
Abstract: Reinforced masonry block retaining walls are comprised of a narrow column of stacked blocks at their exposed end. This column is placed on a nonstructural leveling pad to facilitate the placement of facing units. Theoretically, ...
A Voronoi FE Fatigue Damage Model for Life Scatter in Rolling Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It has been widely accepted that the microstructure of bearing materials can significantly affect their rolling contact fatigue (RCF) lives. Hence, microlevel topological features of materials ...
A Discrete Element Approach for Modeling Cage Flexibility in Ball Bearing Dynamics Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A model for deep-groove and angular-contact ball bearings was developed to investigate the influence of a flexible cage on bearing dynamics. The cage model introduces flexibility by representing ...
A Voronoi Finite Element Study of Fatigue Life Scatter in Rolling Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Microlevel material failure has been recognized as one of the main modes of failure for rolling contact fatigue (RCF) of bearing. Therefore, microlevel features of materials will be of significant ...
Analysis of EHL Circular Contact Shut Down
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, an isothermal study of the shut down process of elastohydrodynamic lubrication under a constant load is performed. The surface mean velocity is decreased linearly from the initial ...
A New Approach for Including Cage Flexibility in Dynamic Bearing Models by Using Combined Explicit Finite and Discrete Element Methods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this investigation, a new approach was developed to study the influence of cage flexibility on the dynamics of inner and outer races and balls in a bearing. A 3D explicit finite element ...
Design and Prototyping of a Force-Reflecting Hand-Controller for Ultrasound Imaging
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents detailed design, analysis, prototyping, and testing of a novel force-reflecting hand-controller allowing physicians to control a robotic wrist and perform ultrasound examinations ...
