NUMERICAL AND EXERIMENTAL MODELING OF RIGID JOINT OF LAYERED WOODEN STRUCTURES

Abstract

The article deals with the problems of modeling and solving contact problems in the ANSYS software complex using the example of calculating the rigid joint of a glued wooden beam. Comparative calculation data for a continuous beam and a beam with a joint in the middle on pasted carbon fiber nails are given. The possibilities of using contact elements between different materials taking into account the nonlinearity of the formulation of the problem are described. The figures of stresses and displacements in the elements are shown. Experiments for determination of the bearing capacity of the joint and determine the nature of structural failure are provided. Conclusions are made about the possibility of modeling composite materials in the environment of the software complex ANSYS in the real structures design
