An enhanced unfolding Inverse Finite Element Method (IFEM) has been used together with an extended strain-based forming limit diagram (EFLD) to develop a fast and reliable approach to predict the feasibility of the deep drawing process of a part and determining where the failure or defects can occur. In the developed unfolding IFEM, the meshed part is properly fold out on the flat sheet and tre...

We study models for surface growth with a wetting and a roughening transition using simple and pair mean-field approximations. The simple mean-field equations are solved exactly and they predict the roughening transition and the correct growth exponents in a region of the phase diagram. The pair mean-field equations, which are solved numerically, show a better accordance with numerical simulati...

In a contact-density chain-growth study we investigate the solubility-temperature pseudophase diagram of a lattice polymer in a cavity with an attractive surface. In addition to the main phases of adsorbed and desorbed conformations we find numerous subphases of collapsed and expanded structures.

We have performed multi-canonical chain-growth simulations of a polymer interacting with an adsorbing surface. The polymer, which is not explicitly anchored at the surface, experiences a hierarchy of phase transitions between conformations binding and nonbinding with the substrate. We discuss the phase diagram in the temperature-solubility plane and highlight the transition path through the fre...

Some dynamic properties of a fourteen-vertex model defined on the bcc(001) surface are investigated with Glauber kinetics. Exact results are given for small-size versions of the model. Using Monte-Carlo simulations on large systems and the Becker-Doering law behaviour of the growth rate in the 2D-nucleation theory, a non-equilibrium phase diagram is

water quality in each area, indicates the impact of geology, climate and anthropogenic pollutants. monitoring of water quality in most cases result in complex data which shows the perfect act of water resources, so they need appropriate method for analyzing. in this study hydro-chemical evaluation of hiv basin which located in west of hashtgerd have been done. to measure the concentration of ma...
