Mechanics of intelligent materials and composite materials
Research and development of experimental and numerical methods for determination of complex thermomechanical properties of intelligent polymeric materials such as magnetorheological elastomers and plastomers (MREs and MRPs), shape memory polymers (SMPs) and polymeric foams (PFs). The behavior of these materials is controlled by external magnetic, electrical, light or heat fields. Development of material models based on description of internal structure and experimentally determined parameters. Mathematical
modeling of complex thermomechanical properties of these materials. Numerical simulation of the response of these materials using the finite element method
