Multi-mechanism Modeling of Inelastic Material Behavior. Georges Cailletaud, Lakhdar Taleb, Kacem Sai. Structural multi-mechanism model with anisotropic damage for cerebral arterial to describe the anisotropic and damage behavior of cerebral arterial tissue. Multi-Mechanism Modeling of Inelastic Material Behavior [Georges Cailletaud] Rahva Raamatust. A new class of constitutive equations (the multi-mechanism models) devoted to the material behavior, for instance of steel, has developed during the last years . The atomistic and molecular mechanisms that occur during mechanical deformation of natural and hierarchical multi-scale modeling capable of providing a bottom-up description of chemically 2.1 Ductile versus brittlematerials behavior: Crystalline solids Physical foundations of elasticity: Chemistry and mechanics. Theinelastic behavior that is the subject of viscoplasticity is plastic deformation For metals and alloys, viscoplasticity is the macroscopic behavior caused by amechanism linked to the In 1934, Odqvist generalized Norton's law to the multi- axial case. Constitutive modeling of cyclic relaxation and ratcheting (cumulative inelastic effectively model multi-axial cyclic elastic–plastic material behavior [20] and [21]. Plastic multimechanism characterization of a specific hardening functional of theories of viscoelasticity and viscoplasticity for the modeling of inelastic properties. Energy dissipation mechanisms—dashpots, inelastic material behavior, etc.—are often included . Elements used in one-dimensional models of viscoplastic materials. The arterial tissue is modeled as a non-linear, incompressible and inelastic material. By an equation of state model with linear elastic shear behavior. A physically-based model for describing material behaviour is in- troduced by Based on this theory, we formulate a multi-mechanism model according to [2] as an transformation expansion strain tensor and εin the inelastic strain tensor. In this work, we introduce a structural multi-mechanism model which can describe the nonlinear, anisotropic, inelastic behavior of cerebral arteries.
