Natural Strain
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The purpose of this paper is to present a consistent and thorough development of the strain and strain-rate measures affiliated with Hencky. Natural measures for strain and strain-rate, as I ...
The Effect of Matrix Microstructure on Thermally Induced Residual Stresses in SiC/Titanium Aluminide Composites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper examines the effect of varying the microstructural composition of titanium aluminide on the evolution of residual stresses in titanium aluminide matrix composites. An analytical model ...
Viscoplastic Model Development With an Eye Toward Characterization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A viscoplastic theory is developed that reduces analytically to creep theory under steady-state conditions. A viscoplastic model is constructed within this theoretical framework by defining material ...
Elastic Model for Crimped Collagen Fibrils
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A physiologic constitutive expression is presented in algorithmic format for the nonlinear elastic response of wavy collagen fibrils found in soft connective tissues. The model is based on the ...
Transverse-Isotropic Elastic and Viscoelastic Solids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A set of invariants are presented for transverse-isotropic materials whose gradients produce strain fields, instead of deformation fields as is typically the case. Finite-strain theories for elastic ...
Fractional Order Viscoelasticity of the Aortic Valve Cusp: An Alternative to Quasilinear Viscoelasticity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Background: Quasilinear viscoelasticity (QLV) theory has been widely and successfully used to describe the time-dependent response of connective tissues. Difficulties remain, however, particularly ...
