An approximate description of non-linear viscoelastic materials
International Journal of Non-Linear Mechanics, 1970Abstract An approximate description of non-linear viscoelastic behaviour is proposed and applied in analysis of creep phenomena of a polyvinyl chloride. The description is based upon the concept of regions of linear and non-linear behaviour, and superposition of linear and non-linear strain components. It is shown that creep and recovery creep can be

Contact melting materials with non-linear properties
Heat and Mass Transfer, 1997The effects of nonlinear thermophysical properties on thermal and flow fields of the molten thin layer produced by contact melting are investigated. The molten layer is assumed to be a non-Newtonian fluid which has temperature-dependent viscosity and thermal conductivity.

Non-linear materials and large displacements
1992Abstract The present chapter provides a brief introduction to techniques for the solution of non-linear finite element problems. The two main types of nonlinear problem are those where the magnitudes of the stresses, displacements velocities, and so on, are sufficient to alter the nature of the constitutive relationships or to make ...

Material figures of merit for non-linear optics
Thin Solid Films, 1991Figures of merit are developed for materials possessing both second-order and third-order non-linear optical properties. These merit figures are then evaluated and tabulated for a number of materials and material classes widely used in existing non-linear optical applications.

Contact-impact Problems with Material non-linearities
1993Abstract In the preceding chapter, it was assumed that contact bodies consist of linearly elastic materials. The linearly elastic material model is valid for most materials only under a certain loading level. When the stress or the strain within the material reaches a certain level, the deformation of the material will no longer be ...
