Generally, adhesives are viscoelastic-plastic materials, for which the development of viscosity and plasticity varies depending on the type of adhesive and the stress state. Various models exist to represent the yield surface, or the so-called elastic limit, taking into account the two stress invariants, hydrostatic stress and von Mises equivalent stress. Moreover, to develop precise pressure-dependent constitutive models, it is necessary to have a large experimental database in order to accurately represent the adhesive strains which are strongly dependent on the tensile-shear loading combination. Under quasi-static loadings, for a given strain rate range viscous effects can be neglected, but only a few experimental results are available to model the... |

We provide a new experimental investigation of the neutrality theorem of Warr (1983), according to which “when a single public good is provided at positive levels by private individuals, its provision is unaffected by a redistribution of income". Our experimental design differs from Chan et al. (1996) in that we redistribute within each group the total group endowment after 10 rounds, instead of comparing different income distributions across groups. We need therefore to control for the “restart effect” (Andreoni, 1988). To do so, we compare our two test-treatments, an unequalizing redistribution (EI) and an equalizing redistribution (IE), to two benchmark treatments for which the same sequence of 10 rounds is repeated twice either with an equal... |
