Currently, solving problems based on designing and calculating
complex structures with significant nonlinearity usually
require:Semi-inverse Method in Nonlinear Problems of Axisymmetric
Shells Forming provides an alternative method for solving problems
with deep geometric and physical nonlinearity. Easily implemented
on normal PCs, this method is fast and creative. The reader can use
integrated packages of the MathCad variety that implement 'live
mathematics'. Such packages give the reader the freedom to create
programs for themselves.In the proposed method, a function for
molding pressure is constructed, which is output to a stationary
value by varying the shape parameters and edge reactions. The final
shape of the shell is given using analytical approximations.
Applications of the method are applied to real shell structures.
Forming spherical and ellipsoidal shells (flapping membranes),
correcting the shape of the bottom of a container for liquid cargo,
modeling the operation of a flat jack, and converting a cylindrical
shell into a barrel-shape are also considered.
