RISBond Characteristics of Earth Block Masonry
Publisher: American Society of Civil Engineers
Abstract: Earth block construction offers a low energy alternative to conventional low-rise building materials such as clay fired masonry units, concrete, processed timber, and steel framed construction. Used to some extent in areas ...
A Fixed-Point Iteration Method With Quadratic Convergence
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fixed-point iteration algorithm is turned into a quadratically convergent scheme for a system of nonlinear equations. Most of the usual methods for obtaining the roots of a system of ...
A Viscoplastic Model for Single Crystals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A viscoplastic constitutive model is described in which deformation behavior is postulated on representative slip systems and the behavior of the entire crystal is determined by summing the slip ...
Viscoplastic Model Development With an Eye Toward Characterization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A viscoplastic theory is developed that reduces analytically to creep theory under steady-state conditions. A viscoplastic model is constructed within this theoretical framework by defining material ...
Stress Versus Temperature Dependence of Activation Energies for Creep
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The activation energy for creep at low stresses and elevated temperatures is associated with lattice diffusion, where the rate controlling mechanism for deformation is dislocation climb. At higher ...
Implementation of a Viscoplastic Model for a Plasma Sprayed Ceramic Thermal Barrier Coating
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes the implementation and modification of a previously proposed unified viscoplastic constitutive model to simulate the behavior of a Yttria Stabilized Zirconia plasma sprayed ...
Development of a Direct Tensile Test for Compacted Earth Blocks Reinforced with Natural Fibers
Publisher: American Society of Civil Engineers
Abstract: Many thousands of years after its development, unburnt earth block masonry continues to offer an environmentally sustainable and cost-effective alternative to other conventional wall building materials, such as concrete ...
Extending the Theory of Creep to Viscoplasticity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A viscoplastic theory is developed that reduces to creep theory analytically under steady-state conditions. A fairly simple model is constructed from this theoretical framework by defining material ...
High Temperature Inelastic Deformation Under Uniaxial Loading: Theory and Experiment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The elevated temperature, uniaxial inelastic deformation behavior of a Ni-base alloy, B1900 + Hf, has been investigated by performing isothermal tensile, creep, cyclic, stress relaxation, and ...
Three Dimensional Modeling of the Hydrodynamics of Oblique Droplet-Hot Wall Interactions During the Reflood Phase After a LOCA
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During the reflood phase, following a loss-of-coolant-accident (LOCA), the main mechanism for the precursory cooling of the fuel is by convective heat transfer to the vapor, with the vapor being ...
