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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
