Phase Transitions in Elastoplastic Materials : Thermodynamical Theory and Numerical Simulation
نویسندگان
چکیده
A general condition of nucleation in elastoplastic materials is derived and specified for dilatational phase transitions (PT). The work integral in the nucleation criterion is calculated numerically after solution of a set of boundary-value problems using finite elements method. The example of the relation between applied axial stress, volumetric transformation strain and PT temperature is determined numerically. Effect of superimposed hydrostatic pressure is taking into account analytically.

NUMERICAL SIMULATIONS OF THE PHASE TRANSITIONS IN CLUSTERS
We have studied the phase transitions in atomic clusters by molecular dynamics simulation, assuming Lennard-Jones interatomic pair potential. Calculations are performed by DAP parallel computer. The results are analyzed by simulating their orientational distribution plots (dot-plot), and neutron diffraction patterns. It is shown that all the main features of the bulk phase transitions are e...
متن کاملPhase Transitions in Inelastic Materials at Finite Strains: A Local Description
A general theory of phase transitions (PT) in the material point of simple inelastic materials with arbitrary constitutive equations is developed. The standard thermodynamical approach can be applied only after averaging of thermodynamical parameters, related to PT, over a PT duration. A PT criterion for the material point is derived, taking into account the temperature variation and dissipatio...
متن کاملDisorder-driven phase transitions of the large q-state Potts model in three dimensions
– Phase transitions induced by varying the strength of disorder in the large-q state Potts model in 3d are studied by analytical and numerical methods. By switching on the disorder the transition stays of first order, but different thermodynamical quantities display essential singularities. Only for strong enough disorder the transition will be soften into a second-order one, in which case the ...

Abstract In this paper elastoplastic buckling of rectangular plates with different boundary conditions are investigated. Differential governing equations of plate are obtained on the basis of general loading and according to deformation theory (DT) of plasticity. Various loading conditions contain uniaxial, biaxial and shear are studied. The employed material is AL7075T6 which is usually used...
متن کاملChaos and Statistical Mechanics in the Hamiltonian Mean Field model
We study the dynamical and statistical behavior of the Hamiltonian Mean Field (HMF) model in order to investigate the relation between microscopic chaos and phase transitions. HMF is a simple toy model of N fully-coupled rotators which shows a second order phase transition. The canonical thermodynamical solution is briefly recalled and its predictions are tested numerically at finite N . The Vl...
