Information × Registration Number 0222U001895, 0120U101775 , R & D reports Title Investigation of the stability of reinforced composite materials and shell elements of structures with them with different types of geometrical and structural imperfections popup.stage_title Head Nazarenko Volodymyr M., Registration Date 04-02-2022 Organization Institute of Mechanics. S.P. Tymoshenko of the National Academy of Sciences of Ukraine popup.description2 A computational model for the study of near-surface buckling in the structure of layered composite materials at an inhomogeneous subcritical state is presented. The obtained results allow to analyze the combined influence of the structure of the composite material and the complex conditions of surface loading on the critical parameters of the stability of the composite material. A computational model for the study of internal and near-surface buckling in the structure of composite material, weakly reinforced with short fibers during compression along the direction of reinforcement parallel to the free surface is presented. The obtained results allow to analyze the influence of the free surface on the critical parameters of the stability of the composite material.  Product Description popup.authors Bystrov Victor M Velichko Larisa G Dekret Volodymyr A Dovzhik Mikhailo V Zhukova Nataliia B Zagorodniuk Olena M Zelenskii Valerii S Kipnis Oleksandr L.
