RISDynamics of Activation Energy and Nonlinear Mixed Convection in Darcy-Forchheimer Radiated Flow of Carreau Nanofluid Near Stagnation Point Region
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this research work, heat and mass transport and radiated, two-dimensional, steady, incompressible nanofluid flow of non-Newtonian material (Carreau fluid) over a stretchable moving surface of sheet is examined. The flow ...
Elastoplastic Nonlinear Analysis of Flexibly Jointed Space Frames
Publisher: American Society of Civil Engineers
Abstract: Conventional approaches to the design and analysis of steel frames commonly assume the structure to be of either simple or rigid construction. In the simple construction approach, connections between members are not capable ...
Bearing Signal Separation Enhancement with Application to a Helicopter Transmission System
Publisher: American Society of Civil Engineers
Abstract: Bearing vibration signal separation is essential for fault detection of gearboxes, especially where the vibration is nonstationary, susceptible to background noise, and subjected to an arduous transmission path from the ...
Nonlinear Analysis of Thin‐Walled Structures Using Least Element/Member
Publisher: American Society of Civil Engineers
Abstract: The paper presents the derivation of a deformation stiffness matrix for an asymmetric thin‐walled beam‐column element. This matrix
Efflorescence Control in Calcined Kaolin-Based Geopolymer Using Silica Fume and OPC
Publisher: ASCE
Abstract: Efflorescence has been an ongoing issue facing the development of geopolymers; excess efflorescence may disturb the stability of the binder microstructure. This paper investigates the controlling of efflorescence in a ...
Elasto‐Plastic Analysis of Box‐Beam‐Columns Including Local Buckling Effects
Publisher: American Society of Civil Engineers
Abstract: A nonlinear finite element procedure for the pre‐ and postbuckling analysis of thin‐walled box‐section beam‐columns is presented. The influence of local plate buckling upon the overall ultimate buckling behavior of the ...
Characterization of Alkali-Activated Nonwood Biomass Ash–Based Geopolymer Concrete
Publisher: American Society of Civil Engineers
Abstract: The combustion ash of a common nonwood biomass (wheat straw) was evaluated for value-added use in production of geopolymer concrete where alkali aluminosilicate hydrates are the primary binder constituents. The wheat straw ...
Elasto‐Plastic Finite Element Models for Angle Steel Frames
Publisher: American Society of Civil Engineers
Abstract: The paper compares two elasto‐plastic models for incorporating the effects of material nonlinearity into a finite element procedure in the large deflection analyses of angle beam columns and trusses. These are the fiber ...
Finite Element Method for Buckling Analysis of Plate Structures
Publisher: American Society of Civil Engineers
Abstract: A finite element method using thin‐plate elements is presented. The method is capable of predicting the buckling capacity of arbitrarily shaped thin‐walled structural members under any general load and boundary conditions. ...
