(PDF) Modelling and numerical simulation of martensitic

Modelling and numerical simulation of martensitic transformation 465 three-dimensional simulations have been performed by Klou cek and Luskin [44, 45]. They ho wever used a A Simulation of Martensitic Transformation of the thermodynamics and kinetics of martensitic transformation. Numerical simulation was conducted for the martensitic transformation at three cooling rates to figure out the relation between volume fraction and temperature at different cooling rates, and martensite phase transformation characteristics at room temperature.

Numerical Simulation of Residual Stress in P91 Repair

The type IV cracking is one of the main reasons for service failure. The repair welding is implemented to solve this problem. The residual stress in P91 repair welding incorporating martensitic transformation (MT) is acquired through finite element simulation. In the simulation, the ABAQUS and the user subroutines FILM, DFLUX, HETVAL, USDFLD, UEXPAN and UHARD are adopted. Numerical simulation of martensitic transformations in Jan 01, 1998 · We have performed molecular-dynamics (MD) simulations of martensitic nucleation processes in iron-based transition-metal alloys. In order to handle a sufficiently large number of atoms in the simulation process, use has been made of the embedded-atom method (EAM).

Sep 01, 2008 · In the simulation, several phenomena, i.e. phase transformation, transformation plasticity, and damage, are taken into account, and a damage equation is proposed based on the continuum damage mechanics (CDM). A set of flat notched bars are simulated and the numerical results in good agreement with experimental results. Numerical simulations of the pseudoelastic effect in May 26, 2020 · ture regarding numerical simulations of these systems. In this paper, a numerical algorithm that is able to simulate the pseudoelasticity associated with the austenite to martensite transition and a subsequent martensite to marten-site transformation is presented. The model considers that all martensitic transformations and retransformations occur at Procedure of numerical simulation of martensitic phase May 16, 2008 · A model, algorithm, and software for a finite-element simulation of the martensitic phase transformation in a small volume of a sample material in the deformation under quasihydrostatic conditions (in a gasket without a pressure medium) in diamond anvils of a superhigh-pressure apparatus have been developed.

Jun 01, 2000 · We introduce a fast numerical method for the evaluation of the effective elastic energy in martensitic polycrystals in two and three dimensions. The overall complexity of the method is ON operations, where N is the number of component crystallites. Upper and lower bounds on the energy are also presented which allow us to estimate the accuracy of the numerical results.
