... as a means of further stabilizing the stress-strain curve evaluation. The characteristics of the inverse solution are investigated using experimental data from bending and uniaxial tests. 10 12 2008 04 02 2009 03 09 2009 bending differential equations inverse problems stress-strain...

...G. J. Tsamasphyros; Th. K. Papathanassiou; S. I. Markolefas In this paper, we derive some analytical solutions of the Kamal cure rate differential equation. The Kamal model is a first order quasilinear ordinary differential equation, describing the progress of the curing reaction of several...

... for the loss of ellipticity of the differential equations and for the strain localization. A general localization criterion is given to determine when numerical solutions cease to show convergence. This criterion is based on an analysis of the determinant of the acoustic tensor, which includes the material...

...Aaron J. Hade; A. Jeffrey Giacomin A numerical solution is presented for isothermal Newtonian wire coating under vacuum or with an externally applied pressure. Differential equations for the melt cone shape are derived from a force balance on the melt cone. Die design curves are then constructed...
