RISA General Fatigue Theory and Its Application to Out-of-Phase Cyclic Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Results of an experimental investigation of a constant-amplitude, fully reversed biaxial tension-compression out-of-phase cyclic loading are presented first. An energy-based fatigue theory is extended ...
An Experimental Study on the Effect of Prior Plastic Straining on Creep Behavior of 304 Stainless Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Constant strain-rate plastic straining followed by creep tests were conducted to investigate the effect of prior plastic straining on the subsequent creep behavior of 304 stainless steel at room ...
A Rate-Dependent Inelastic Constitutive Model—Part II: Creep Deformation Including Prior Plastic Strain Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this part, a constitutive model for creep deformation is presented, which includes the effect of prior plastic straining. The model is capable of predicting the influence of plastic or creep ...
A Rate-Dependent Inelastic Constitutive Model—Part I: Elastic-Plastic Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this part a rate-dependent elastic-plastic constitutive model is presented which is an extension of our earlier rate-indpendent model. The effect of prior creep on the subsequent inelastic ...
Nonproportional Multiaxial Cyclic Loading: Experiments and Constitute Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Biaxial tension compression, deformation controlled, out-of-phase cyclic tests were conducted on thin-walled circular cylindrical specimens of a low alloy carbon steel. The influence of strain ...
Biaxial Ratcheting Under Strain or Stress-Controlled Axial Cycling With Constant Hoop Stress
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Strain or stress-controlled tension-compression cyclic tests were conducted on pressurized thin-walled tubular specimens of 304 stainless steel. In strain-controlled mode ratcheting strains in hoop ...
A Finite Elastoplastic Constitutive Formulation With New Co-rotational Stress-Rate and Strain-Hardening Rule
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A constitutive model for finite elastoplastic deformations is presented. This model incorporates two novel features: first, a strain-hardening law that is applicable to complex loading paths and ...
In-Phase and Out-of-Phase Multiaxial Fatigue
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this investigation, thin-walled circular cylindrical specimens fabricated from a low alloy pressure vessel steel (ASTM A-516 Gr. 70) were subjected to various multiaxial loading conditions. The ...
Determination of Forces in a Magnetic Bearing Actuator: Numerical Computation With Comparison to Experiment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Calculations of the forces exerted on a journal by a magnetic bearing actuator are presented, along with comparisons to experimentally measured forces. The calculations are based on two-dimensional ...
Fracture Toughness of Highly Ordered Carbon Nanotube/Alumina Nanocomposites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fracture toughness of highly-ordered multi-wall carbon-nanotube-reinforced alumina composites is calculated from experimental data on nanoindentation cracking. A combined analytical and numerical ...
