Abstract Determination of earth pressures is one the fundamental tasks in geotechnical engineering. Although many different methods have been utilized to present passive pressure coefficients, influence non-associated plasticity on problem has not discussed intensively. In this study, finite-element limit analysis and displacement are applied for frictional materials. Results compared with sele...

my paper has two parts. first, i talk about the golden rule. after introducing the rule and its global importance, i explain why many scholars dismiss it as a vague proverb that leads to absurdities when we try to formulate it clearly. i defend the golden rule against such objections. second, i talk about the golden rule in persia and islam; i consider persian sources (muslim and non-muslim) an...

Accurate material behaviour and its response to loading are needed for a reliable calibration of ductile failure criteria. Non-quadratic yield functions often necessary such description. Nevertheless, it leads the prediction stress states that inconsistent with expected deformations in contradiction experiments when associated flow rule is adopted. These problems may be solved by applying less ...

in iran’s system of tripartite collective bargaining, does the wage-policy maker consistently react optimally to the best move made by the exchange rate-policy maker (nash-rule) or only to the state of economy (non-nash rule)?. this paper not only investigates the nature of the political game (nash rule against non-nash rule) but also estimates some structural parameters by using 2sls method an...

In this paper, a stress integration algorithm is presented for a generalized elasto-plastic material model governed by the three stress invariants I1, J2 and J3. The methodology is successfully applied to the Mohr–Coulomb material model with a non-associated flow rule and implemented in ADINA.

analysis of non-laminar flows in coarse alluvial beds has a wide range of applications in various civil engineering, oil and gas, and geology problems. darcy equation is not valid to analyze transient and turbulent flows, so non-linear equations should be applied. non-linear equations are classified into power and binomial equations. binomial equation is more accurate in a wide range of velocit...
