TL;DR: In this article, the acentric factors of cesium, rubidium and potassium were determined on the basis of the generalized van der Waals equation of state (GVWAS).
Abstract: The acentric factors of cesium, rubidium and potassium are determined on the basis of the generalized van der Waals equation of state. This generalized equation differs from the known van der Waals equation of state by the third parameter n in the expression for molecular pressure. The results of the determination of the acentric factors of cesium, rubidium and potassium are in good agreement with experimental data.

TL;DR: In this paper, a thermo-mechanical one dimensional constitutive model based on the use of strain and temperature as control variables is presented, which is able to reproduce the basic responses of shape memory material such as super elasticity, shape memory behavior, pseudoelasticity, single variant martensite reorientation process.
Abstract: This paper present a thermo-mechanical one dimensional constitutive model based on the use of strain and temperature as control variables and able to reproduce the basic responses of shape memory material such as super elasticity, shape memory behavior, pseudoelasticity, single variant martensite reorientation process. The model time integration is performed and a robust algorithm for solution of the time discrete model is addressed together with algorithmically consistent tangent. The model is implemented in NITINOL wire (Ni-Ti-6% Cu) which is used to simulate the above mentioned responses. The Thermomechanical response at different temperatures compare well with experimental and numerical results.
