Purpose: The goal of this investigation was to characterize the compliance properties in selected polymers used for temporary (provisional crown and bridge) applications. Method: Polymethyl methacrylate (PMMA)- and polyethyl methacrylate (PEMA)-based JET and TRIM II were investigated along with two bisacryl composite resins (LUXATEMP and PROTEMP 3 GARANT). Rectangular samples of the resins were...

Abstract

In [4] we presented a new approach to data analysis based on flow distribution study in a flow network, called here a flow graph. The introduced flow graph differs from that proposed by Ford and Fulkerson [1], Branches of the flow graph are interpreted as decision rules, whereas the flow graph is supposed to describe a decision algorithm. Hence, we propose to model decision processes as flow gr...

The orientation of the fibers in UHPC is decisive for tensile strength and failure components. mold filling strategy during casting structural components dictates flow routing thus fiber orientation. In addition, also affects behavior suspension. measurements rheological properties concrete rheometers, strongly scattering often occur. this paper, a novel model viscoplastic fluids investigated C...

A nonlocal constitutive formulation for a porous ductile material is investigated, in which delocalizadon relates to the damage mechanism. An elastic-viscoplastic material model is used, with delocalization incorporated in terms of an integral condition on the rate of increase of the void volume fraction. Two model problems are analysed to study the effect of including this material length, one...
