Surface construction for orthrotropic perfectly elastic-plastic Murnaghan material

The problem of constructing a yield surface is described. The magnitude of the stress velocity potential is explained graphically. The parameters of an elastic-plastic process are introduced: a modified R. Schmidt parameter and an analogue of the Lode parameter, the sign of which changes only when the singular point of the plasticity curve passes. The formal work area of the Murnaghan law is calculated, the real area will be much smaller. An effect similar to the Bauschinger effect for the deviator of the stress tensor is assumed to be fair. In the basic experiments of uniaxial and biaxial tension, compression and shear, a piecewise-linear generator with vertices at the corresponding singular points of the plasticity curves is determined. The magnitude of the effect is approximated by a quadratic dependence in the place parameter and piecewise-linear one in the hardening parameter. According to the magnitude of the effect, at the point of the active process there is a singular point of the curve, into which the basic generator moves. The yield surface is constructed by ductility curves drawn through the generator. Determination of the magnitude of the effect under repeated loading after unloading is considered.

THE IMPACT OF INTELLECTUAL CAPITAL ON THE MARKET VALUE AND PERFORMANCE OF THE COMPANY

Intellectual capital as a driver of growth and development of technically and technologically intensive companies in the era of knowledge economy is the basic generator of creating superior company performance. The conditions of the “new economy” influenced the change of the business model of modern companies, whereby the identification, measurement, reporting, control and exploitation of the intellectual capital of the company became important in order to maximize the value of owners and other stakeholders of the company. The subject of this paper is to examine the impact of intellectual capital components on the financial and market performance of enterprises. This paper aims to show the degree of connection and direction of movement of financial and market performance of companies in relation to the concentration of intellectual capital in companies.

Experimentation on Geopolymer Concrete Added with Silica Fume

Concrete is the world's generally versatile, solid and dependable improvement material. Close by water, concrete is the most utilized material, which required enormous proportions of OPC. Standard OPC creation is the second just to the vehicle as the basic generator of carbon di oxide, which dirtied the earth. Notwithstanding that colossal all out criticalness was in like way devoured for the strong creation. Along these lines, it is unavoidable to locate an elective material to the current generally over the top, most asset debilitating OPC. Geopolymer bond is a creative headway material which will be passed on by the produced development of inorganic particles.This paper quickly outlines the constituents of geopolymer solid, its quality and potential applications.
