RISA Constitutive Model of Cyclic Plasticity With a Nonhardening Strain Region
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: By introducing the concept of a nonhardening region in the plastic strain space, a constitutive model is proposed for cyclic plastic loadings between variable, as well as fixed, strain limits. ...
Detailed and Simplified Elastoplastic Analyses of a Cyclically Loaded Notched Bar
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To find some features in the development of cyclic hardening in structural components with areas of strain concentration, detailed and simplified elastoplastic analyses are performed on an ...
A Constitutive Model of Cyclic Plasticity for Nonlinear Hardening Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A constitutive model is proposed for cyclic plasticity of nonlinear hardening materials. The concept of a cyclic nonhardening range, which enables us to describe the dependence of cyclic hardening ...
Uniaxial Ratchetting of 316FR Steel at Room Temperature— Part II: Constitutive Modeling and Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Uniaxial ratchetting experiments of 316FR steel at room temperature reported in Part I are simulated using a new kinematic hardening model which has two kinds of dynamic recovery terms. The ...
Evaluation of Creep Constitutive Equations for Type 304 Stainless Steel Under Repeated Multiaxial Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Four kinds of creep constitutive models, i.e., strain-hardening, modified strain-hardening, kinematic-hardening, and mixed-hardening theory, are evaluated on the basis of creep-test results on type ...
Experimental Evaluation of Creep Constitutive Equations for Type 304 Stainless Steel Under Non-Steady Multiaxial States of Stress
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to evaluate the validity and limitations of the creep-hardening surface model proposed by the present authors, a series of creep tests for type 304 stainless steel were performed at ...
Constitutive Modeling of Anisothermal Cyclic Plasticity of 304 Stainless Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Temperature-history dependence in anisothermal cyclic plasticity of 304 stainless steel is studied for the constitutive modeling within the temperature range from room temperature to 600°C. ...
A Constitutive Model of Creep Describing Creep Recovery and Material Softening Caused by Stress Reversals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The constitutive model of creep proposed by the present authors on the basis of a creep-hardening surface in creep strain space (CHS model) is first modified to incorporate creep recovery. It ...
On the Acoustic Nonlinearity of Solid-Solid Contact With Pressure-Dependent Interface Stiffness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nonlinear interaction between elastic wave and contact interface, known to result in the so-called contact acoustic nonlinearity, is examined in a one-dimensional theoretical framework. The present ...
Creep Behavior of a Unidirectional SCS-6/Ti-15-3 Metal Matrix Composite at 450°C
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As the first step to understand the creep behavior of a unidirectional SCS-6/Ti-15-3 metal matrix composite, creep tests were performed at 450°C using specimens reinforced with fibers oriented ...
