Abstract
The dynamic behavior of thin-wall
members manufactured from materials with
the pyroelectric effect was studied. A
variational formulation of the problem
is used, and a variational principle is
formulated that differs from the well-
known one. Correct boundary-value
problems describing the tension,
compression, and bending of a thin-wall
pyroelectric member are constructed
using the variational principle and a
number of hypotheses on the distribution
of the components of physical fields
along the width of the member. P. 162-
