Cyclic Plasticity: Some Properties of the Hysteresis Curve of Structural Metals at Room Temperature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The hysteresis curve in the transient and steady-state stage is characterized by inequalities and periodicity conditions for the tangent to the hysteresis curve (dσ/dε) and its derivative (d2 ...
NSF Workshop on Inelastic Constitutive Equations for Metals: Experimentation-Computation-Representation
Publisher: The American Society of Mechanical Engineers (ASME)
Discussion: “Energy Approach for Creep-Fatigue Interactions in Metals at High Temperatures” (Fong, J. T., 1975, ASME J. Pressure Vessel Technol., 97, pp. 214–222)
Publisher: The American Society of Mechanical Engineers (ASME)
The Rate (Time)-Dependent Behavior of Ti-7Al-2Cb-1Ta Titanium Alloy at Room Temperature Under Quasi-Static Monotonic and Cyclic Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Uniaxial tests using a servocontrolled testing machine and strain measurement at the gage length were performed on a high-strength, low-ductility Titanium alloy. Tests involved monotonic and cyclic ...
The Hardening and Rate-Dependent Behavior of Fully Annealed AISI Type 304 Stainless Steel Under Biaxial In-Phase and Out-of-Phase Strain Cycling at Room Temperature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thin-walled tubes were subjected to fully reversed strain-controlled axial (A), torsional (T), in-phase (I) and out-of-phase (O) loading. A computer controlled MTS axial-torsion servocontrolled ...
An Analysis of the Two-Bar Ratcheting Behavior Using the Viscoplasticity Theory Based on Overstress (VBO)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The ratcheting behavior of the “unsymmetric two-bar system” was investigated by numerical experiments. The two bars are restrained to the same length and are subjected to a constant load. One ...
A Finite Element Time Integration Method for the Theory of Viscoplasticity Based on Infinitesimal Total Strain
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A forward gradient method is employed in the formulation of a time integration scheme for the theory of viscoplasticity based on total strain. The theory uses a viscosity function and an ...
A Uniaxial Damage Accumulation Law for Time-Varying Loading Including Creep-Fatigue Interaction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A differential form for damage accumulation is proposed wherein the rate of damage accumulation is equal to a product of two functions. The first depends only on the present damage and the ...
The Influence of Test Temperature on the Ratchetting Behavior of Type 304 Stainless Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The zero-to-tension ratchetting behavior was investigated under uniaxial loading at room temperature and at 550, 600, and 650°C. In History I the maximum stress level of ratchetting was ...
Construction of Nonlinear Monotonic Functions With Selectable Intervals of Almost Constant or Linear Behavior
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A rather general method is given to construct classes of functions with an arbitrary almost constant (linear) initial interval followed by a nonprescribed interval of monotonic nonlinear behavior. ...
