Sergey Abaimov

M.S. students are welcome to join current research projects:

1. High and giga cycle fatigue
Advisers: I.S.Akhatov, S.G.Abaimov
The goal of this study is to investigate mechanical properties of materials under fatigue loading. Key aspects of investigation are:
- both high and gigacycle fatigue;
- first metals, then composite materials;
- S-N curve and statistics (local and global) of fatigue lifes.
The responsibility of a student will include:
- literature review on the topic;
- finite-element design and analysis of specimens in Abaqus;
- supervise the following specimen manufacturing;
- tests conducted utilizing Shimadzu ultrasonic fatigue testing system 2000;
- microphotograph investigation of failure processes;
- post-processing of results in MatLab or Mathematica.
2. The influence of porosity on strength of composite materials
Advisers: I.S.Akhatov, S.G.Abaimov
The goal of this study is to investigate the influence of porosity on strength properties of composite materials. The responsibility of a student will include:
- literature review on the topic;
- collaboration with CMND2S BashSU to support specimen manufacturing, tests, and results post-processing;
- develop an analytical micromechanical model predicting strength of composite materials for the given value of porosity.
3. Design and manufacturing of new materials based on additive technologies
Advisers: I.S.Akhatov, S.G.Abaimov
The goal of this study is to design and manufacture a principally new class of materials with unseen so far properties utilizing 3D printing of composites. Students’ responsibilities will include:
- literature review;
- composite 3D printer assembling, repairing, and modification if necessary;
- material design and analysis in Abaqus;
- composite 3D printer programming and specimen manufacturing;
- testing specimens’ mechanical properties.
4. Characterization of the strength of fiber/matrix interface in fiber-reinforced composites
(in collaboration with KULeuven)The goal of this study is to characterize the strength of fiber/matrix interface in fiber-reinforced composite materials. Of particular interest is the interface fracture toughness. Studies will be based on the single fiber fragmentation test when fiber debonding is recorded with the aid of SEM. Later, data should be post-processed by means of digital image correlation technique and supported by the finite-element analysis in Abaqus.

 

Current interests include:

  • fluid mechanics,
  • composite materials,
  • micromechanics,
  • fatigue,
  • damage mechanics,
  • statistical physics,
  • phase transitions.

Education:

  • M.S. with honor (Moscow Institute of Physics and Technology)
  • PhD (University of California, Davis)
  • C.Ph.-M.S. (RAS)
