Constitutive equations for thermomechanical deformations of glassy polymers
Poly-Carbonate (PC) and Poly-Methyl-Methacrylate (PMMA) are lightweight and mechanically tough transparent glassy polymers. Their mechanical behavior at low to moderate strain rates has been well characterized; however, that at high strain rates needs additional work. We propose two modifications to existing pressure-dependent viscoplastic constitutive equations that enable one to simulate bett...
متن کاملConstitutive Analysis of Large Elasto- Plastic Deformation Based on the Multiplicative Decomposition of Deformation Gradient
Abstract-By using Lee’s (1969. 1. Appf. hfech. 36, l-6) multiplicative decomposition of the deformation gradient into its elastic and plastic part of Hill and Rice’s (1973. SlAbf J. Appf. Math. U, 44S-461) constitutive framework. explicit and consistent constitutive analysis of large clastoplastic deformation is given. Both isotropic and anisotropic material behaviour is considered. so that som...
متن کاملElasto-Plastic Constitutive Model for Finite Element Simulation of structural Adhesives
Considered by the automotive industry as a good solution to bond car body parts together, structural adhesives must be integrated in the early design process of vehicles, hence in the finite element analysis. A first difficulty when modeling structural adhesives comes from their complex mechanical pressure-dependent behaviour as well as their load-dependent strength. These aspects make them imp...
متن کاملError estimates for elasto-plastic problems
— Under some reasonable smoothness assumpfions on the displacements, we are able to dérive an error estimate of the form ||a — <7h||L2{fl)^ Ch, for the approximation of the stress field a in some problems in elasto-plasticity. Using the same ideas, we als o find a piecewise line ar approximation of Mosolov's problem, for which we still get an 0 (h) error estimate.
متن کاملTailoring Physical Aging in Super Glassy Polymers with Functionalized Porous Aromatic Frameworks for CO2 Capture
A series of chemically functionalized porous aromatic frameworks (PAFs) have been synthesized and deployed within mixedmatrix membranes for gas separation. This series of PAFs delivered for the first time simultaneous control of selective gas transport and physical aging within the membranes. New composites including native and metalated fullerenes were also prepared, and the composites exhibit...
