DEVELOPMENT OF METHODS FOR CALCULATING REINFORCED COMPOSITES USED IN CONSTRUCTION

Authors: P. Geradze , P. Kipiani, S. Mindadze


Abstract:

The paper dwells on numerical method of research of new designs of the latticed shells by using mathematical programming, to produce such constructions, which have high strength in one direction, and high flexibility in another direction, and for which, the use of reinforced composites is highly effective. In research, using a micro-model of composite material, taking into account the arrangement of mutually intersecting reinforcing threads, the winding angle and the coordinate system related to threads, there has been obtained a boundary problem, which is solved by method of linearization. In research, it is possible to take into account the impact of the winding angle, mechanical properties and cylindergeometry on strength of the latticed shells.

Keywords: latticed shells; composite materials; numerical research; attached coordinate system.
