Materials Mechanics Research Group (MAME)

1. Introduction

Materials Mechanics Research Group (MAME) is founded by Ton Duc Thang University. MAME focuses on modern problems in material science and engineering that require the physics-based predictive dislocation theory as well as the effective and accurate computational methods to identify the material parameters and simulate the material behavior of metals and alloys.

2. Mission and vision

MAME has three main tasks:

- Build the clear and suitable orientations in the scientific research, consisting of solving the mechanical problems and publishing the high quality journal papers.

- Organize regular seminars, conferences, meeting with various national and/or international research groups. These scientific activities help members of MAME to be supported, improved, and educated in major fields of Materials Mechanics.

- Perform transfer of technology such as consulting, supporting, transferring, applying engineering and technology in Materials Mechanics.

3. Research topics

The research focus of Materials Mechanics Research Group is Thermodynamic Dislocation Theory involving disorder temperature. We intend to develop the theory for both uniform and non-uniform plastic deformations and apply it to various engineering problems in material science and metallurgy. This includes:

- Disorder temperature and irreversible thermodynamics;

- Energy and dissipation of dislocated crystals;

- Statistical and homogenization methods;

- Parameter identification using the least squares analysis;

- Numerical methods of solution of practical problems.
