...Junzhou Yang; Jianjun Wu; Dongshen Yang; Qishuai Wang; Kaiwei Wang; Zengkun Zhang; Mingzhi Wang; Muhammad Muzamil A physically based constitutive model with internal state variables (ISVs) is established, it is used to describe the flow stress and microstructure evolution of Ti–6Al–4V alloy...

...Bhasker Paliwal; Youssef Hammi; Mei Chandler; Robert D. Moser; Mark F. Horstemeyer A new dynamic strain rate-dependent elasto-viscoplastic damage constitutive model for ultrahigh-performance concrete (UHPC) is developed by incorporating Duvaut–Lions viscoplasticity generalized to multisurface...

... associated with the orientation of the crystallographic grains. The life model accounts for fatigue, creep, and environmental damage under both isothermal and thermomechanical fatigue (TMF). Ni-base superalloy thermomechanical fatigue creep-plasticity constitutive model TMF is a complex...

... the container wall on residual stress in glass The simulation of a representative thin slice through the glass and steel with an elastic-viscoplastic constitutive model of the glass, conducting gap elements, and a generalized plane strain condition reasonably matches measurements of both temperature...

... micromechanical properties constitutive model stress-strain behavior polyethylene damage mechanics semicrystalline amorphous The mechanical behavior of polymers has been the subject of considerable studies in the past. One important research aim consists in developing models for understanding...

.... Elastomer foam materials have very complicated material behaviors. The prediction of the rate responsive behavior is one of the most interesting topics in elastomer material modeling. The focus of this article is to present a unique method for deriving the rate dependent constitutive model of an elastomer...

... processed by SPD requires a constitutive model reflecting changes in material behavior with grain refinement. A basis for this is provided by a constitutive description developed by Kocks et al. ( 7 8 9 10 ), which efficiently describes the deformation behavior of a broad range of materials in terms...

...Yan Wang; Ellen M. Arruda A microstructually motivated, three-dimensional, large deformation, strain rate dependent constitutive model has been developed for a semi-crystalline, blended, thermoplastic olefin (TPO) ( Wang, Y., 2002, Ph.D. thesis, The University of Michigan, Ann Arbor, MI ). Various...

.... This “saw-tooth” pattern is a result of stretch-induced unfolding of modules along the molecular chain and is speculated to play a governing role in the function of biological materials and structures. In this paper, constitutive models for the large strain deformation of networks of modular macromolecules...

...Rebecca B. Dupaix; Dwarak Krishnan Recently, a hyperelastic-viscoplastic constitutive model was developed for PET and the noncrystallizing copolymer PETG ( R. B. Dupaix, Ph.D. thesis, MIT, 2003 ). The materials were found to behave very similarly under monotonic loading conditions and the single...

.... The effect of finite temperature is accounted for via the local harmonic approximation, which relates the entropy to the vibration frequencies of the system, and the latter are determined from the interatomic potential. The focus of this theory is to establish the continuum constitutive model in terms...
