چکیده

We use successive datasets from the U.K. Family Expenditure Survey to estimate a closed form consumption function for households facing uncertain future income. The closed form is derived from a model of absolute risk aversion modi ̄ed to re°ect di®erences in consumers' circumstances (quasi-relative risk aversion). Proper adjustment is made for demographic effects. Plausible estimates for the intertemporal substitution parameter are found. However an encompassing test shows that a naive Keynesian model has some residual explanatory power.

A CLOSED-FORM NON- LINEAR SOLUTION FOR PLASTIC FLANGE WRINKLING OF CIRCULAR PLATES IN DEEP DRAWING PROCESS

This paper deals with two-dimensional plane stress wrinkling model of a plastic annular plate. Based on energy method and the nonlinearity of strain-displacement law, a bifurcation function in polar coordinates is derived analytically. This technique leads to the critical conditions for the onset of the plastic wrinkling of flange during the deep drawing process. To find this solution, the Tres...

A Corotational Elastic Constitiutive Model and its Application to the Analysis of a Large Deformation Closed Cycle

In this paper, an elastic constitutive model based on the Eulerian corotational rate of the logarithmic strain tensor is proposed. Using this model, the large deformation of a closed cycle containing tension, shear, compression and inverse shear is analyzed. Since the deformation path includes a closed cycle and the material is considered as an isotropic elastic material, the normal and shear c...

NORMAL FORM SOLUTION OF REDUCED ORDER OSCILLATING SYSTEMS

This paper describes a preliminary investigation into the use of normal form theory for modelling large non-linear dynamical systems. Limit cycle oscillations are determined for simple two-degree-of-freedom double pendulum systems. The double pendulum system is reduced into its centre manifold before computing normal forms. Normal forms are obtained using a period averaging method which is appl...
