Problems of micromechanics of composites and structures under various interface conditions

Exploitable results

A rigorous investigation of the problems of micromechanics of composites and structures under various interface conditions with a special emphasis on interaction of structural elements and defects in the microstructure of composites has been carried out. The study has been performed within the framework of the most exact approach based on the model of a piecewise-uniform medium with application of the equations of the three-dimensional linearised theory of the deformable bodies stability (TLT-DBS). These results obtained are free from simplifications and hypotheses on the stress-strain state characteristic for approximation approaches. Main attention has been given to the fibrous, laminated and other composite materials and structures. The studies included exact problem statements, construction of general solutions of spatial and plane problems at homogeneous subcritical states, and development and substantiation of effective analytical and numerical methods for solving the problems. Spatial and plane problems for fibrous and laminated composite materials with taking into account various interface conditions, the presence of cracks, the interaction of structural elements and defects in the microstructure of composites and edge effects have been studied. The micro-/macro-interaction in sandwich shells have been analyzed within the framework of semi-analytical-numerical approaches. Short-wave buckling of the face layers (face wrinkling) have been considered under combined compression and bending. Conclusions on the regularities of the mentioned phenomena have been drawn. Analysis of approximate calculation schemes in the micromechanics of composite materials as well as the analysis of results for laminated materials has been performed. On the basis of the results obtained, recommendations for calculation methods in engineering have been formulated.
