The paper describes the LOGOS software package functionality implemented in 2017-2018 to extend the methods of simulating the static strain processes for thing-walled structures, including those made of laminar composites. These methods and algorithms are constructed on the base of a shell finite element. Successful implementation of the described functional capabilities is demonstrated by the example of solving static strain problems for structural components of aircrafts, including those made of composites. Keywords: LOGOS software package, LOGOS-SA module, stress-strain state, shell, a laminar composite, physical nonlinearity, geometrical nonlinearity.
