【 摘 要 】

A model of a high-order triangular spectral shell element is presented to calculate a stress-strain state of a shell construction under small deformations considering the material inhomogeneity. Consideration of shear deformations, changes in the thickness of a shell is implemented through the use of 7-parameter model of shell elements. The results of problems solving are to illustrate the possibilities of the element.
