RISGeneration of Hourly Ambient Temperature from Generalized Cumulative Frequency Distributions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present article is devoted to make available a method to generate hourly ambient temperature values when the monthly average hourly ambient temperature, T̄ah is known. Cumulative frequency ...
Some Studies on Scuffing Performance of Surface Treated AISI 4340 Steels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Scuffing or scoring is an important form of damage leading to component replacements in lubricated mechanical systems such as power drives, gears, bearings, cams and followers, piston rings etc. ...
Structural Dynamic System Reconstruction Method for Vibrating Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To determine the natural frequencies and damping ratios of composite laminated plates, we present an efficient modal parameter estimation technique by developing a residual spectrum based structural ...
Secondary Flow Control Using Vortex Generator Jets
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, results are presented of an experimental investigation into the effectiveness of vortex generator jets in controlling secondary flows in two-dimensional S-duct diffusers. The ...
Thermal EHL of Rough Rolling/Sliding Line Contacts Using a Mixture of Two Fluids at Dynamic Loads
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The behavior of the thermal elastohydrodynamic lubrication film in rough rolling/sliding line contacts at dynamic loads is investigated numerically. The lubricant is assumed to be a mixture of ...
Mixing and Entrainment Characteristics of Circular and Noncircular Confined Jets
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present work deals with the experimental investigation of entrainment characteristics of confined/semiconfined circular and noncircular jets. The jet fluid, after issuing out of a nozzle of ...
Some Studies on Life Prediction of Thermal Sprayed Coatings Under Rolling Contact Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Design of engineering components is concerned with their strength and durability characteristics. While design for strength is influenced by the bulk material characteristics, the design for ...
A Displacement Equivalence-Based Damage Model for Brittle Materials—Part I: Theory
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a displacement equivalence-based damage model for brittle materials is proposed. A new damage deactivation criterion, which depends on both the stress and strain states of the ...
A Displacement Equivalence-Based Damage Model for Brittle Materials—Part II: Verification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper focuses on the application of the damage model for brittle materials proposed in the preceding paper on theory. The evolution rule of damage derived using the Onsager relations is ...
Hybrid Analysis Method for Reliability-Based Design Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Reliability-based design optimization (RBDO) involves evaluation of probabilistic constraints, which can be done in two different ways, the reliability index approach (RIA) and the performance ...
