Theory of shells

Zhilin's early works, Ph.D. [1] and Professor theses were devoted to the development of the theory of shells. When Zhilin started his research in this area, there existed no general theory of shells. For each class of shell-type constructions there were developed particular independent theories: the theory of thin single-layer shells; the theory of engineering anisotropic shells; the theory of ribbed shells; the theory of thin multi-layer shells; the theory of perforated shells; the theory of cellular shells; the theory of thick single-layer shells, and many others. Within each theory one could distinguish several versions, which differed in basic assumptions as well as in final equations. The theories of shells are still being developed since the science gives birth to new constructions that can not be described within the existing variety of theories. Zhilin created (1975 - 1984) the general nonlinear theory of thermoelastic shells, whose way of construction fundamentally differs from the one of all known versions of shell theories, and can be easily generalised for any shell-like constructions and other objects of continuum mechanics. This approach is comprehensively described in work [2 - 4].
