Analysis of an Idealized Directionally Solidified FCC Material
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Directionally solidified materials are being increasingly used in aircraft engines. These alloys are anisotropic due to the well aligned crystalline structure with additional considerations including ...
An Analysis of High Temperature Metal Creep—Part I: Experimental Definition of an Alloy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The general objective of the research reported is to develop a constitutive theory for the elevated temperature behavior of Wrought Udiment 700. A major part of this work was to establish a ...
Problems in Damage Analysis Under Nonproportional Cycling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper uses examples to illustrate problems in damage analysis under nonproportional cycling. Nonproportional histories examined include multiaxial loading with either fixed or rotating principal ...
An Analysis of High Temperature Metal Creep—Part II: A Constitutive Formulation and Verification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A phenomenological development of a constitutive equation is presented for the high temperature viscoplastic flow of a metal. The development rests on a viscoelasticity foundation but incorporates ...
A Unified Constitutive Model for the Inelastic Uniaxial Response of Rene’ 80 at Temperatures Between 538C and 982C
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this research is to develop a constitutive equation for the uniaxial monotonic and cyclic response of Rene’80 between the temperatures of 538C and 982C. The constitutive equation ...
A Constitutive Model for the Inelastic Multiaxial Response of Rene’ 80 at 871C and 982C
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper contains an extension of the uniaxial state variable constitutive model of Ramaswamy et al. (1988) to the case of multiaxial loading. The correlation between uniaxial and multiaxial ...
