Abstract: Nonlinear constitutive equations are developed and used to predict from constant stress data the creep behavior of 2618 Aluminum at 200°C (392°F) for tension or torsion stresses under ...

Abstract: Combined tension and torsion creep experiments are reported in which (A) one stress component was increased or decreased while the other remained constant; (B) one stress component was removed ...

Abstract: An energy-based algorithm is developed for dynamic absorbers with adaptable stiffness to suppress structural vibrations via real-time parametric control actions. A controller with multi-objective ...

Abstract: Experiments are reported for stress relaxation and simultaneous stress relaxation and creep with proportional and nonproportional loading and unloading. Results were compared with predictions of a ...

Abstract: Creep and recovery data are presented for combined tension and torsion of 2618 Aluminum at 200°C (392°F). These data are represented by a mechanical-mathematical model in which the ...

Abstract: A structural vibration control concept, using piezoelectric materials shunted with real-time adaptable electrical networks, has been investigated. The variable resistance and inductance in an external ...

Abstract: This paper presents the use of x-ray tomography imaging to reconstruct a three-dimensional (3D) digital representation of individual particles in a granular system. The granular system is represented by the mass center ...

Abstract: Soil fabric quantities such as doublet vector and branch vector distributions are important in doublet mechanics and micromechanics modeling of soil behavior. The quantification of these quantities is therefore imperative ...

Abstract: This paper presents three approximate Riemann solver schemes, namely: the flux vector splitting (FVS), the flux difference splitting (FDS), and the Osher scheme. Originally used to solve the Euler equations in aerodynamic ...
