The work purpose in creation, on the basis of the nonlinear theory of thin anisotropic shells, settlement models and carrying out of researches of the tensely deformed condition, stability and after the critical behaviour of covers under the influence of compressing loadings, torsion. Research methods: analytical Bubnov-Galerkins, the decision of the nonlinear differential equations - Newton-Kantorovichs, numerical discrete orthohonalization, asymptotic Kojters. Scientific novelty of the received results consists that: the method concerning construction of system of the differential equations of the nonlinear theory of thin anisotropic shells is developed; at use of the listed methods new problems about the nonlinear tensely deformed condition of anisotropic shells as zero, so double curvature are solved; new decisions of problems of stability and initial after the critical behaviour of anisotropic flat and not flat shells are received. Results of work can be used at designing anisotropic shells systems in the research, industrial enterprises and establishments.
