STUDY OF STRESS-STRAIN STATES OF A REGULAR HINGE-ROD CONSTRUCTIONS WITH KINEMATICALLY ORIENTED SHAPE CHANGE

Abstract

For regular hinge-rod structures, an engineering method for analyzing the stress-strain state is devel­oped, taking into account the transformation of the form by folding repeated fragments of the structure. For the software implementation of the proposed calculation algorithm, a macro is compiled in the APDL language, which is built into the ANSYS software package. A step-by-step procedure that simulates the transformation of the farm geometry was tested.
