Multicomponent TMD Phase-field model with elastic heterogeneity
نویسنده
چکیده
A generalized semi 2D-model for the structural transformations under mechanical strains of multi-components transition metal dichacogenide (TMD) monolayers were manipulated. In this model, not only the chemical and structural but also elastic heterogeneity, through the eigen strain method, were introduced. Basing on this model, some experimental observation can be simulated and understood better. Some qualitatively pre-results related to these phase transformations were obtained by this model, some of them are interesting and still need further study.

Study of Love Waves in a Clamped Viscoelastic Medium with Irregular Boundaries
A mathematical model is presented to investigate the effects of sandiness, irregular boundary interfaces, heterogeneity and viscoelasticity on the phase velocity of Love waves. Geometry of the problem is consisting of an initially stressed viscoelastic layer with corrugated irregular boundaries, which is sandwiched between heterogeneous orthotropic semi-infinite half-space with initial stress a...
متن کاملTransference of SH-Waves in Fluid Saturated Porous Medium Sandwiched Between Heterogeneous Half-Spaces
A mathematical model is considered to investigate the behavior of horizontally polarized shear waves (SH-waves) in fluid saturated porous medium sandwiched between heterogeneous half-spaces. Heterogeneity in the upper half-space is due to linear variation of elastic parameters, whereas quadratic variation has been considered for lower half-space. The method of separation of variables and Whitta...
متن کاملDynamics of Love-Type Waves in Orthotropic Layer Under the Influence of Heterogeneity and Corrugation
The present problem deals with the propagation of Love-type surface waves in a bedded structure comprises of an inhomogeneous orthotropic layer and an elastic half-space. The upper boundary and the interface between two media are considered to be corrugated. An analytical method (separation of variables) is adapted to solve the second order PDEs, which governs the equations of motion. Equations...
متن کاملTopical Review
The phase-field method is reviewed against its historical and theoretical background. Starting from Van der Waals considerations on the structure of interfaces in materials the concept of the phase-field method is developed along historical lines. Basic relations are summarized in a comprehensive way. Special emphasis is given to the multi-phase-field method with extension to elastic interactio...

In this talk, we report some of recent works with current and former colleagues at Penn State (S. Das, M. Li, C. Liu, R. Ryham, X. Wang and J. Zhang) on the phase field modeling and simulations of the vesicle membrane deformation under elastic bending energy and the interaction with background fluid flows and other external fields. We discuss the relations between the phase field model and the ...
