Fracture in mode I using a conserved phase-field model.
We present a continuum phase-field model of crack propagation. It includes a phase-field that is proportional to the mass density and a displacement field that is governed by linear elastic theory. Generic macroscopic crack growth laws emerge naturally from this model. In contrast to classical continuum fracture mechanics simulations, our model avoids numerical front tracking. The added phase-f...
متن کاملHyperbolic non-conserved phase field equations
We consider the following hyperbolic system of PDEs which generalize the classical phase field equations with a non-conserved order parameter / and temperature u: u tt #e2/ tt #c 1 u t #e2c 1 / t "a*u, e2/ tt #c 2 e2/ t "e2*/#f (/)# eu for e@1. We present the model, derive a law for the evolution of the interface which generalizes the classical flow by mean curvature equation, and analyze the e...
متن کاملa study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
the effect of using model essays on the develpment of writing proficiency of iranina pre-intermediate efl learners
abstract the present study was conducted to investigate the effect of using model essays on the development of writing proficiency of iranian pre-intermediate efl learners. to fulfill the purpose of the study, 55 pre- intermediate learners of parsa language institute were chosen by means of administering proficiency test. based on the results of the pretest, two matched groups, one as the expe...
Universality class of absorbing phase transitions with a conserved field
We investigate the critical behavior of systems exhibiting a continuous absorbing phase transition in the presence of a conserved field coupled to the order parameter. The results obtained point out the existence of a new universality class of nonequilibrium phase transitions that characterizes a vast set of systems including conserved threshold transfer processes and stochastic sandpile models.
